Summary

Triangle Networks

United Kingdom · AI-generated

business fibre uk wholesale

TRIANGLE-AS is operated by Triangle Networks Ltd.

What it's used for

  • The address space carries business connectivity and infrastructure, evidenced by reverse DNS entries such as network.trianglenetworks.co.uk and mail.studio-hive.co.uk, alongside legacy space registered to AnlX IP Network Services.
  • With 4,608 IPv4 addresses announced across 4 prefixes and 61 observed neighbours, the high neighbour-to-address ratio indicates a transit or wholesale role rather than a large-scale residential access network.
  • Traffic from this AS consists of full-fibre gigabit connectivity for businesses, voice and data services, and backhaul for partner networks across the UK.

Notable

  • Registrants align with the announcer for the majority of the inventory, with Triangle Networks Ltd listed for 185.14.136.0/22 and 185.179.208.0/22, while 81.91.96.0/21 is registered to AnlX IP Network Services and 213.146.186.0/23 to Cogent Communications Hostmaster.
  • The inventory includes a mix of modern Triangle Networks space and older blocks associated with AnlX and Cogent, suggesting historical acquisitions or leased capacity.
  • The address inventory is finely subdivided into four distinct IPv4 prefixes and three IPv6 prefixes, consistent with a corporate estate managing multiple service segments.

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 1,779 prefixes, as published 2026-10-21. 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.
