Summary
Nominet UK
dns infrastructure registry legacy
Nominet UK (NOMINET) is the registry for the .uk top-level domain — the not-for-profit company that runs the .uk namespace and the authoritative DNS behind it. This AS carries Nominet's own registry and DNS infrastructure.
What it's used for
- Registry systems and authoritative name service. Sampled rDNS lands on Nominet's own core estate (
nominet.org.ukfirewalls and switches, datacentre device names), not on any customer or subscriber population. - About 9,500 IPv4 addresses across a handful of RIPE prefixes, plus a notably large IPv6 footprint (roughly as many v6 prefixes as v4) — the shape of a DNS operator rather than an access network.
- Every announced block is registered to Nominet itself (
NOMINET-CORE-DC1-*,NOMINET-DCBnetnames, GB).
Notable
- This is critical-infrastructure address space with no honest classification in a hosting/ISP vocabulary: it is neither an eyeball network, a hosting provider, nor a transit carrier. It is deliberately left unclassified rather than forced into one, in the same way root-DNS and IXP ASNs are.
- Nominet peers widely (dozens of BGP neighbours) despite its small address count, which is what an anycast DNS platform looks like.
Interesting
- Beyond
.uk, Nominet has operated registry back-end and protective-DNS services for other parties, so a query hitting this space is not necessarily a.uklookup.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 446 networks and 1,852 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
