Why do we need an IPv6 checker?

The free online IPv6 connection checker helps you check if the site you need supports this address protocol. If the answer is yes, then you can use inexpensive and reliable IPv6 proxies. If the answer is no, then for entertainment or work you will need to buy generic IPv4 proxies that cost more.

Why don't all sites support IPv6 proxies?

For work, business development and entertainment, you can use proxies of two address protocols - IPv4 and IPv6. The first was developed back in the 80s, it is time-tested, debugged and reliable. The second appeared later and its main task was to solve Problems with the limited number of IPv4 addresses. When the first protocol was developed, no one imagined how widespread the Internet would be and how many addresses it would need to function. Therefore, a stock of four billion IP addresses seemed more than enough. But in an environment where even sockets and kettles are connected to the network a shortage of free IPs began to appear.

But there are 340 undecillion addresses in the IPv6 protocol (that's 36 zeros after the number) and this number is really enough for a long time. In addition, this protocol has a number of other advantages - better encryption, optimized routing, easier administration.

A large number of addresses also significantly reduces the price of IPv6 proxies, which makes them a very profitable solution for bulk actions in SEO, traffic arbitrage or SMM.

However, IPv6 support requires sites to modernize , and not everyone is ready to make such a waste of time and resources.In addition, the availability and low price of IPv6 makes IPv6 proxies the main choice for DDoS attacks.Because of this, many sites do not trust IPv6 addresses and block them.As a result, with all the advantages of the new address protocol, not all sites support it and you need to check them for compatibility before using a proxy.
