What Is IPv6 and Why Check It?
IPv6 (Internet Protocol version 6) is the new version of the internet protocol designed to replace IPv4. The main difference is a 128-bit address space (instead of 32-bit in IPv4), providing virtually unlimited addresses: 3.4 x 10^38 versus 4.3 billion in IPv4.
More and more websites and services are migrating to IPv6. Checking for AAAA records on a domain shows whether the site supports IPv6 connections. This is important for: testing proxy compatibility, verifying server configuration, and planning IPv6 migration.
How Does the Tester Work?
The tool performs a DNS AAAA query for the specified domain. If the domain has IPv6 addresses, they are displayed in a table. If there are no AAAA records, the domain operates only on IPv4.
IPv6 and Proxies
Proxies with IPv6 addresses have several advantages: they're cheaper (IPv6 addresses are abundant), less likely to be blacklisted, and better suited for working with modern services. GProxy offers IPv6 proxies at competitive prices.
FAQ
What if a domain doesn't support IPv6? This is normal for many sites. They operate on IPv4 only and are accessible through regular proxies.
Can I connect to an IPv6 site through an IPv4 proxy? No, accessing IPv6 resources requires an IPv6 proxy or a dual-stack connection.
