Summary

ISIX Communications

United Kingdom · AI-generated

business vpn uk

The AS handle ISIX-CLOUD-AS is held by ISIX Communications LLP.

What it's used for

  • The address space carries corporate and service endpoints, evidenced by netnames such as UK-ISIX-20160818, UK-ISIX-20180511, and VELAR-NET.
  • The inventory consists of 1792 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale business or internal network rather than a transit provider.
  • Traffic from this AS represents office workers, web/API endpoints, and VoIP media for ISIX Communications, a UK-based limited liability partnership that provides connectivity services.

Notable

  • Registrants for all announced prefixes align with the announcer, listing ISIX Communications NOC and ISIX Communications LLP, with one prefix also listing Velar Solutions OU.
  • The address inventory is finely subdivided into small /23 and /24 blocks, consistent with an internal corporate estate or a small service provider managing specific site 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: 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.
