What is
IPv6?
IPv6 is the next-generation Internet Protocol that provides a much larger address space than IPv4. IPv6 support ensures your domain is accessible via both IPv4 and IPv6 addresses.
Why it
matters.
IPv6 is becoming increasingly important as IPv4 addresses are exhausted. Businesses should support IPv6 to ensure accessibility for all customers, especially as more networks transition to IPv6-only. It also demonstrates modern infrastructure and future-proofing.
What can
go wrong.
Without IPv6 support: your domain may become inaccessible to IPv6-only networks, you may lose customers as IPv6 adoption increases, and you fail to meet modern internet standards. IPv6-only networks are becoming more common, especially in enterprise environments.
Technical
details.
IPv6 support requires: 1) AAAA DNS records for your domain (IPv6 addresses), 2) AAAA records for name servers, 3) IPv6 connectivity for both name servers and web server, 4) Same content served on both IPv4 and IPv6. We check for AAAA records and test connectivity to verify IPv6 is properly configured.
