Summary

Nocsult Ltd

United Kingdom · AI-generated

business telecom uk small

The AS handle NOCSULT is held by Nocsult Ltd.

What it's used for

  • The address space carries customer traffic, as indicated by the netname Nocsult-Customers for 147.78.7.0/24 and the registrant ABUSE ICI LIR for 81.180.249.0/24.
  • The network announces 512 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio consistent with a small access or business network rather than a transit provider.
  • Nocsult Ltd is a telecommunications company based in Chertsey, Surrey, and the traffic from this AS consists of business and customer connectivity services.

Notable

  • Registrants for the announced prefixes are ABUSE ICI LIR and Abuse-C Role, which differ from the AS holder Nocsult Ltd, suggesting the address space may be leased or managed by a different entity.
  • The address inventory is small and fragmented, consisting of two /24 blocks with no IPv6 prefixes announced.

Reputation

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
