Summary

Catalyst2

United Kingdom · AI-generated

hosting vps uk business

CATALYST2-AS is operated by Catalyst2 Services Ltd.

What it's used for

  • The address space carries dedicated hosting and VPS services, evidenced by netnames UK-POUNDHOST-20040816 and CATALYST2-DEDICATED-123CONNECT, and reverse DNS entries such as 84-18-197-126.vps.catalyst2.com.
  • The AS announces 7936 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a role focused on hosting and dedicated server provision rather than transit.

Notable

  • Registrants for the majority of prefixes are listed as AS29550 Operators; Team Blue Carrier Limited, while the AS holder is CATALYST2-AS Team Blue Carrier Limited, suggesting a shared operational entity or historical relationship between the two ASes.
  • The inventory consists of contiguous blocks within the 84.18.192.0/20 range, with one smaller /24 block registered under a different netname.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
