Summary

Nomios UK&I

United Kingdom · AI-generated

business cybersecurity managed-services

NOMIOS-ASN is operated by Nomios UK&I Limited.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname UK-INFRADATA-20190312 and the registrant Nomios UK&I Limited.
  • The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and web/API endpoints for a cybersecurity and managed services provider.

Notable

  • Registrants align with the announcer, listing Nomios UK&I Limited and UK-INFRADATA-TECH-ROLE.
  • Infradata rebranded to Nomios, consolidating operations in Belgium, Germany, The Netherlands, Poland, and the United Kingdom into the Nomios Group.
  • The inventory consists of a single /22 IPv4 block and a /29 IPv6 prefix, reflecting a compact, segmented corporate address space.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 1,781 prefixes, as published 2026-10-16. 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.
