IPV4 AND IPV6 – WHAT IS THE DIFFERENCE?
An Internet Protocol (IP) address is a unique numeric identifier for a specific device on the network. Currently, there are two valid versions of addresses – IPv4 and IPv6. At first glance, their main difference lies in the length of the address space. For the fourth version, this is 32 bits and 128 bits for IPv6. In reality, the differences are much greater.
IPv4 Exhaustion
The fourth version of the Internet protocol was created in 1981 and is still considered the main one. IPv4 addresses consist of four decimal numbers of 1 byte, separated by dots. For example: 12.34.56.78. Since the length of the Internet Protocol version 4 address is 4 bytes or 32 bits, the number of IP addresses also has its limitations. This understanding led to the development of a new version of IP with a large address space back in the 1990s. With the growth of devices and the development of networks, the issue of IPv4 exhaustion became more and more obvious.
This is not surprising, since the Internet was developed for military and scientific purposes. Who would have imagined that each person can have several gadgets and devices. Not to mention smart cars, vacuum cleaners, and light bulbs that also need their own addresses. This development was not predicted at all.
Initially, IPv4 addresses used class addressing, which had to be abandoned in the direction of switching to classless CIDR technology, and then to NAT, the network address translation mechanism. Despite attempts at scaling, the address allocation process began to overtake the capabilities of the IPv4 architecture itself.
In 2011, the IANA address space Administration allocated the last 5 /8 IPv4 blocks to Internet registrars. In 2012, RIPE started distributing the last /8 block. In total, there are about 4.29 billion IPv4 addresses in the world. Upgrading to the Internet Protocol version 6 is considered the only solution to the problem of running out of IP addresses.
The transition to a new version of the IP protocol is considered a natural and inevitable process of technology development. Both versions of addresses are already used, but the number of IPv6 addresses will increase over time. The IPv4 address space will run out sooner or later, and new devices that will be released may not support the old protocol version in their basic settings. Cisco and D-Link vendors have already enabled IPv6 by default in their router settings. All this will complicate the work with IPv4 and one day it will be deprecated.
IPv6 version
The Protocol was created in 1996 as a replacement for its predecessor. In 2012, the ISOC organization and several major Internet services conducted worldwide testing of the new protocol. The success of this event proved the readiness to implement IPv6.
The IPv6 address space is 128 bits or 16 bytes, which is four times the size of the previous version. This allows you to meet the needs of Internet users with a huge number of addresses. IPv6 consists of hexadecimal numbers separated by colons. For example: 1234:0ABC:0000:0011:0000:0000:0000:00AA. For ease of use, the address is abbreviated in one of the following ways: for example: 1234: ABC:0:11:0:0:0:AA or 1234:ABC:0: 11::0:AA. IPv6 uses alphanumeric addressing methods.
Advantages of IPv6
- A huge address space, where each device will have its own white address.
- There is no need to use NAT, which is favorable for VPN, peer-to-peer networks.
- More efficient routing due to the hierarchical structure of addresses. Routing tables are significantly smaller than IPv4.
- Automatic creation and configuration of SLAAC addresses, without using a DHCPv6 server (or in conjunction with it).
- More efficient packet handling thanks to optimized headers.
- Mandatory support for IPsec traffic encryption.
- The Internet Protocol version 6 is better compatible with mobile networks than its predecessor.
The number of IP addresses in version 6 is steadily growing. You can view the dynamics of IPv6 distribution by country on a special
Google service. The data is constantly updated. At the time of publication of this article, the total share of IPv6 traffic is about 36%.
IT giants like Google, Amazon, and Facebook have long been working on IPv6.Major hosting providers also provide new versions of addresses to clients when hosting or renting servers in the data center. However, the overall dynamics of the transition from version 4 to version 6 lags far behind forecasts. And there are reasons for this.
Disadvantages of IPv6
- Poor compatibility with existing infrastructure. For providers and companies with large IT infrastructures, switching to the sixth protocol promises financial and time costs. This includes buying new hardware, configuring it, optimizing the network and devices used, updating DNS, and other work.
- IPv6 is not backward compatible with IPv4, so you have to use Dual stack mode during operation, when both versions work in parallel with each other. This leads to double work and potentially reduced security.
- Not everyone fully understands how to properly configure and work with IPv6.
- Ironic as it may seem, but the IP length of the sixth version. Addresses are harder to remember and use in everyday life.

Can I Carding By Using
https://proxy6.net/ ..... Is This Proxies Good ?
Yes, proxies from this provider are suitable for carding.
Why do we need proxies?
Change IP and DNS - You can hide your real IP address and DNS simply by connecting a proxy.
Anonymity in the network - Anonymous and secure use of the Internet, hiding Internet activity from your provider.
Bypass locks - Remove service restrictions based on IP, GEO data, port, and protocol. Your Internet becomes free;
Protection from hackers - Hacker attacks fall on our proxy server. Attackers will not be able to find out the real IP address.
How long does it take to issue a proxy after payment?
The proxy is issued automatically immediately after payment.
If your merchant profile doesn't display proxies immediately, please contact technical support.
How do your proxies differ from all others?
Our proxies are provided exclusively
in one hand -
they are not public.
By purchasing IP addresses from us, you can be sure that only you are using them for your own purposes.
Proxies can be used for various social networks without restrictions.
Proxies are located on non-overloaded servers and the response speed is much higher than that of competitors, which plays a big role in collecting and filtering information.
How do I extend my proxy?
In your merchant profile, go to the "
My proxies", mark the necessary proxies, click "
Extend" and select the extension period. Then you pay the cost of renewing the selected proxies.
Is port 25 open?
No, port 25 is closed. Email distribution is prohibited.
Are payment systems accessible via a proxy?
Qiwi, Paypal, WebMoney, and Yandex don't work in our network.Money, as cases of fraud involving the use of proxies in these payment systems have become more frequent. By a court decision, our network was blocked on these sites, and there is no access to these sites from a proxy.
Is Steam available through a proxy?
No, Steam is blocked in our networks.
Are proxies suitable for BCS (bookmakers)?
No, our proxies are not suitable for working with bookmakers.
What is the minimum proxy rental period?
The minimum lease term for an IPv6 proxy is
3 days.
The minimum lease term for an IPv4 / IPv4 Shared Proxy is
30 days.
Which sites are suitable for IPv6 proxies?
IPV6 proxies are only suitable for sites that
support ipv6, such as:
instagram.com, facebook.com, youtube.com, plus.google.com and
other sites with ipv6 support.
Are IPv6 proxies suitable for parsing?
IPv6 proxies are not suitable for parsing wordstat and keycollector software because wordstat does not support IPv6.
They are not suitable for email newsletters and other similar activities.
Why is IPv6 worse than IPv4 proxy?
Nothing, just not all sites support them.
What do IPv6 proxies look like?
IPv6 proxies are made on the principle of a tunnel from IPv4 to IPv6. The tunnel is necessary for the software to accept proxies correctly. Sites don't see the tunnel address, they only see IPv6, which is hidden on the tunnel port. Each tunnel port has a unique individual IPv6 address.
Example
of what IPv4 - 164.0.32.25:3229 looks like
An example of how
IPv6 looks hidden behind a port is fabc: de12:3456:7890:ABCD:EF98:7654:3210
What is the proxy speed?
IPv4-up to 10 Mbps
IPv4 Shared - up to 10 Mbps
IPv6-up to 30 Mbps
In what proxy format?
Proxies in HTTPs and SOCKS5 format-these formats are currently supported by almost any software.
In your merchant profile, you can change the format of selected proxies on the fly from HTTPS to SOCKS5 and back.
How does authorization work?
Proxy authorization is performed by
username and password, or by
ipaddress.
How do I check whether a proxy is working properly?
Observe the limits and do not hang a lot of accounts on 1 proxy, despite the fact that the proxy is clean, if you do not use the addresses correctly, you can ban them.
You can check the addresses here: yandex.ru/internet
After inserting a proxy in your browser settings, first go to this site from your IP address, and then from the proxy to understand what the difference is.
Alternatively, you can use our free online
proxy checker.
How can I check whether a site or service works with IPv6?
To check whether a site or service supports IPv6, go to
the site-ipv6-support page and enter its address.
Can I replace the proxy?
Replacement is possible
in the first day after purchase for a good reason.
Refund of funds
Guarantee a refund within 1 day of purchasing the proxy. But this does not mean that we will make a refund in any case! A refund is only possible if
the proxy is inoperable, after our verification.
There is no refund for IPv4 Shared Proxy!
When I Go To Buy Proxy They Asked Proxy Period ... What Proxy Period I Need To Give?
Why do I need a test period for a proxy?
Why do I need a test period for a proxy? If you have any doubts when purchasing proxy servers, you can take a trial period for testing to check the validity of IP addresses.
When buying proxy servers, users often don't know how to find a reliable provider. Each store offers its own prices, proxy rental conditions, and related customer service services. Since there are many online stores that sell proxy servers on the Internet, sometimes buyers are confused and can not decide on a choice.
Most sites provide guarantees for their product, check their addresses for functionality, and are ready to reimburse the buyer in case of non-working servers. However, users are usually suspicious of server vendors that they haven't worked with before, or of new stores that have recently entered the market. Such suspicions arise for two reasons.
In the first case, buyers are concerned that the purchased proxies will not work and their money will be wasted.
The second reason for doubts about the purchase is that you don't fully understand the purpose of using a proxy server. Without information about what proxy protocol is required for operation, whether IP binding to a specific region is required, and whether the degree of anonymity of the address is important, users doubt that the purchased proxy servers will be suitable for performing the necessary tasks.
Checking the proxy for validity can help dispel user doubts. There are many different sites that provide the ability to check the proxy using the following parameters:
- server health
- the speed of its operation
- geolocation of an IP address
- protocol type
Many online proxy server stores have access to this feature on their websites, and it is often free of charge.
Service
However, to check the validity of IP addresses, you must first purchase them. People are not ready to buy a product that they are not sure about. With this service, users can purchase several servers for a certain period of time and check them for all the parameters of interest. The proxy trial period allows you to find out whether proxies are suitable for the client's goals, whether they match the description on the site, and how they cope with the task set by the buyer. Some vendors provide a different number of proxies with a test period for free, for a period of 1 to 24 hours.
What Proxies I Need To Buy ? IP4 Or IP6 ?
Comparison of IPv6 and IPv4 protocols
In this article, we will compare the IPv6 and IPv4 protocols, as well as talk about their technical subtleties and differences.
"What is ipv4 and ipv6?" - this question is asked by many users who encounter them and simply cannot understand what exactly the difference is and why both options are still used. In principle, there is nothing complicated in this, since both protocols are elements of the Internet and allow you to freely visit sites, receive information and carry out any other activity on the network.
Technical details
To understand how Internet protocols work, you need to understand the technical details. The operation of the Internet is structured in such a way that each user is assigned an identifier in the form of a numeric value – an IP address (Internet protocol). Servers that host Internet resources are essentially computers with large capacities that are continuously connected to the network, so they, along with ordinary users, are assigned unique IP addresses that ensure interaction between users and sites.
What is known about IPv4?
The concept of configuring IPv4 proxies appeared much earlier than configuring ipv6. This is due to improved technologies and the format of transmitting information to network users. If you can find a lot of information about the first version of the protocol, since everyone is used to it, then there is a little less information about the second, more advanced version. When the IPv4 protocol was created in 1980, the developers did not take into account the possibility of widespread use of addresses around the world, so they limited their number to 4,294,967,296 possible unique addresses.
With the development of technologies, the Internet and devices, there is a shortage in the use of addresses with the protocol version 4. This gave rise to the creation of a protocol with a large number of addresses, so the IPv6 protocol was developed, which allows you to use about 300 million IP addresses for each inhabitant of the earth, which is a huge number that should last for decades. The cost of an IPv6 proxy is significantly lower than an IPv4 proxy. This is due to the large number of free IP addresses on the protocol of the sixth version and the shortage of addresses on the fourth version.
IPv6 what is it?
In practice, IPv6 is a simple module that has a more advanced structure and functionality. This is a more recent version of the protocol, which provides high-speed data processing on the part of the router and high security of network surfing. But if you choose ipv4 or ipv6, which is better? The answer here is unequivocal: IPv6 is a priority protocol, since this version is more advanced and newer. The main problem with using the protocol version 6 is that at the moment not all providers support it. Upgrading equipment for a new type of data transfer costs a lot of money, which significantly slows down the transition process.
This does not mean that you will not be able to work on IPv6 proxies: our proxies are connected via an IPv4 tunnel, so after purchasing an IPv6 proxy from the company proxy-sale.com You won't have to worry about whether the provider has provided IPv6 support - proxies will work stably. In addition, you will not experience any inconvenience - you can use any of the usual programs.
All you need to know is whether the site you need works with the IPv6 protocol at all. There is a special service for checking this. ipv6-test.com/validate.php. You just need to insert a link to the desired site. If it supports this technology, you can use an IPv6 proxy without hesitation. Now let's try to understand the difference between IPv4 and IPv6.
The difference in protocols affected the appearance of IP addresses:
Example:
- IPv4: 139.59.150.159
- IPv6: 2005:0db8:17a3:09d7:1f36:8a2e:00a0:735d
This was caused by an improvement in the type of encryption and an increase in numerical data, due to the need to create a large number of new IP addresses. The IPv6 protocol provides faster data processing speeds and increased security for surfing the web. The sixth version of the protocol has great prospects for use, however, it takes up memory and requires constant user interaction. But IPv4 is an older version, which is a real "titan" of the global network, since virtually all the largest projects and sites use it for a long time, which causes difficulties when changing IPv4 to IPv6.
These are the main differences between the current Internet protocols, which may affect the choice of proxy for working on the Internet.
