Why IPv6 Compatibility Matters

As the internet continues to grow, IPv4 addresses are running out. IPv6 provides a virtually unlimited address space with 340 undecillion unique addresses, ensuring the future scalability of the internet.

What This Tool Checks

Our IPv6 Checker queries the DNS AAAA records for any domain. If AAAA records exist, the domain supports IPv6 connections. This is essential for ensuring your websites and services are accessible to the growing number of IPv6-only networks.

Benefits of IPv6 Adoption

Future-Proof Infrastructure: Prepare for the inevitable transition away from IPv4
Better Performance: IPv6 can offer faster routing and reduced latency
Enhanced Security: IPsec is built into IPv6 by default
No NAT Required: End-to-end connectivity without address translation
