business telecom voip wan

The AS handle COMMS365 is operated by Comms365 Limited.

What it's used for

  • The address space carries infrastructure and business connectivity, evidenced by netnames such as COMMS365-INFRASTRUCTURE and UK-C365LIMITED-20120907.
  • The network announces 21,504 IPv4 addresses across 16 prefixes with 4 observed neighbours, a ratio consistent with an access or business connectivity provider rather than a transit carrier.
  • Traffic from this AS consists of secure connectivity, WAN, and IoT solutions for business clients, including VoIP media and signalling, as Comms365 designs and operates resilient networks for corporate sectors.

Notable

  • Registrants align with the announcer, listing Comms365 Limited and Company Contacts for the majority of prefixes.
  • The address inventory is finely subdivided into multiple /21, /22, /23, and /24 blocks, reflecting site-by-site segmentation for a corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
