About IPv6 Support Checker
The IPv6 Support Checker helps you determine if a website is accessible over the next-generation Internet Protocol (IPv6). As IPv4 addresses become increasingly scarce, more websites are adopting IPv6 to ensure future compatibility.
What does this checker test?
This tool performs two critical checks: (1) it verifies if the domain has AAAA DNS records, which are required for IPv6 connectivity, and (2) it tests if the website can actually be reached via these IPv6 addresses.
Why is IPv6 support important?
- Future-proofing: IPv6 is the future of internet addressing
- Global reach: IPv6-only networks are growing in certain regions
- Performance: Direct IPv6 connectivity can be faster than transitional technologies
- Enhanced security: IPv6 was designed with security features in mind
- Search engine optimization: Some search engines might favor IPv6-ready websites
