What is it?
This DNS finding means the tested hostname did not return usable A or AAAA records. Address records map a hostname to public IP addresses.
Why does it matter?
Browsers, TLS checks, mail checks, and uptime probes need address records before they can connect. If the hostname has no usable address records, the service is effectively unreachable by normal clients.
How to fix it?
Publish an A record for IPv4 and, if supported, an AAAA record for IPv6 at the exact hostname being tested.
www.example.com. 3600 IN A 203.0.113.10
www.example.com. 3600 IN AAAA 2001:db8::10If the hostname is a CNAME, verify that the final target resolves to public addresses and is not blocked by the network guard.
