AAAA Record vs A Record
Compare IPv6 and IPv4 DNS mapping records and understand when each one appears.
A records map hostnames to IPv4 addresses, while AAAA records map hostnames to IPv6 addresses.
Many sites publish both, but troubleshooting gets confusing when only one family is working correctly.
Why it matters
This matters because users, resolvers, and networks may behave differently depending on whether IPv4 or IPv6 connectivity is available.
Recommended next steps
Check both record types, compare how the hostname resolves across networks, and confirm the web stack is ready for the address family in use.
