Nameserver host did not resolve

Markdown-backed fix guides for Amhost Labs audit findings.

What is it?

This DNS finding means a delegated nameserver hostname did not resolve to an A or AAAA address. It belongs to DNS delegation and authoritative nameserver health.

Why does it matter?

Resolvers need to reach authoritative nameservers to answer queries for the domain. If a delegated nameserver host does not resolve, clients may see slow lookups, retry storms, or intermittent DNS failures.

How to fix it?

Publish address records for every nameserver hostname and update registrar glue when the nameserver is inside the same domain.

example.com.       3600 IN NS ns1.example.com.
ns1.example.com.   3600 IN A 203.0.113.53
ns1.example.com.   3600 IN AAAA 2001:db8::53

Remove old delegated nameservers that are no longer active, then compare parent delegation and authoritative zone answers.
