DNS lookup
Everything DNS says about a domain: traced from the root servers down, every record type asked of the domain's own nameservers, each nameserver checked, then every hostname and policy record it points at followed, with SPF, DMARC, DKIM and DNSSEC checked along the way.

Zone bbc.co.uk284 queries in 0.7 s2026-11-09 05:12:38 UTCNot DNSSEC-signed
- Note bbc.co.uk isn't signed with DNSSEC, so resolvers can't tell forged answers from real ones.
Records
Asked directly of dns1.bbc.com (198.51.45.73), an authoritative server: no cache in between, so these are the live values.

Hosts and reverse DNS
Every hostname the records point at, resolved to its addresses; each address's PTR (reverse DNS), with ✓ where the PTR name resolves back to the same address.

Public resolvers
What four public resolvers answer right now, from their caches. Highlighted values differ from the authoritative answer: either a recent change they haven't picked up yet (the TTL says how long until they do), or, for A and AAAA, a CDN or geo-routed site handing each resolver location its own addresses.
