Nameserver & DNS Delegation Audit

Your name servers decide where your domain points — and a broken or inconsistent setup is a hijacking opportunity. This audits a domain's delegation, flags stale or mismatched name servers, sizes how much each provider actually handles, and surfaces registry facts — so you can catch delegation weakness before it's exploited.
