DNS lookup
What is it?
DNS translates domains into addresses and service records used by browsers and mail systems.
Why is it important?
Inconsistent nameservers, propagation problems, or stale records can make services unreachable.
How do you improve it?
Use redundant authoritative nameservers, document changes, and verify public resolver consistency.
