MCP server

is it DNS?

By isitdnsAll Isitdns servers

Live DNS from an independent seat: dig any public resolver, audit or sweep a domain, walk a delegation, read the resolver board.

First seen 2 Oct 2026. One server, whatever directories list it: each directory listing keeps its own page and history.

ToolDescriptionBehaviour
check_domainA site or domain is not working: one call. First line, whether the name resolves. Then the eleven-check audit of its zone, each row ok, warn, fail or skipped, with why.Read-only
digOne record from one public resolver: records, flags, rcode, EDE, latency. DoH from the edge, or Do53 from a region's probe (from). follow: true walks a CNAME chain.Read-only
dnssec_chainThe signed zone cuts from the root to the answer: DS and DNSKEY at each, the first link that breaks or where it goes insecure. Signature bytes are not verified.Read-only
registrationThe registry's RDAP record: statuses and what each means for resolution, the dates, the nameservers. No contacts.Read-only
sweep_domainAfter a zone change: each nameserver's answer to each name and type, the disagreements, lame or silent servers, CAA and ACME readiness.Read-only
traceThe delegation from the root to the authority, like dig +trace: each referral and glue, lame or unreachable servers, the final answer.Read-only
