Summary

Communicate Technology

United Kingdom · AI-generated

business uk enterprise

BLAZE-NETWORKS is the AS handle for Communicate Technology LTD.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames UK-COMMUNICATE-20110919 and UK-COMMUNICATE-20150518 registered to Communicate Technology LTD.
  • The AS announces 3072 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and internal systems for a UK-based technology consultancy that provides cyber and joined-up technology services to organisations.

Notable

  • Registrants for both announced prefixes match the AS holder, Communicate Technology LTD, confirming consistent ownership.
  • The AS handle BLAZE-NETWORKS reflects a historical identity; LinkedIn evidence confirms Blaze Networks Ltd is now part of Communicate Technology, explaining the name discrepancy between the handle and the current corporate entity.
  • The inventory consists of two distinct IPv4 blocks, 188.227.240.0/21 and 185.100.148.0/22, with no IPv6 prefixes announced.

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.
