registry infrastructure dns uk

NOMINETANYCAST is operated by Nominet UK, the registry operator for the .uk and .co.uk domain namespaces.

What it's used for

  • The address space carries registry infrastructure and DNS services, evidenced by netnames UK-NOMINET-20030514, NOMINET, and NOMINET-AP, and reverse DNS entries pointing to nominet.org.uk.
  • With 8,704 IPv4 addresses and 15 IPv6 prefixes announced against 130 observed neighbours, the high neighbour count relative to the address inventory indicates a transit or peering-heavy role typical of a major infrastructure provider.
  • Traffic from this AS consists of DNS resolution queries, registry API interactions, and internal management traffic for the .uk domain ecosystem.

Notable

  • Registrants consistently identify as Nominet UK entities, including Nominet UK Admin and Nominet administrator, aligning with the AS holder.
  • The inventory includes prefixes with netnames UK-DWP and UKNHS-D2U0B, indicating that specific address blocks are allocated to or managed for UK government departments (Department for Work and Pensions, National Health Service) under Nominet's administration.
  • The address inventory is a mix of /21, /22, and /23 blocks, with the largest being 213.248.216.0/21.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
