Summary

Colocation Ltd

United Kingdom · AI-generated

colocation hosting business

The AS handle COLOCATION is held by Colocation Ltd.

What it's used for

  • The space carries infrastructure for Inferno Communications Ltd, evidenced by the netname UK-INFERNOLAN-20191115 and reverse DNS entries pointing to oninferno.net.
  • The network announces 256 IPv4 addresses and 2 IPv6 prefixes against 17 observed neighbours, a ratio consistent with a transit or peering-heavy role rather than a large access network.
  • Traffic from this AS consists of web and API endpoints for Inferno Communications, a UK-based internet service provider, as well as potential colocation services provided by the parent entity.

Notable

  • The RDAP registrant for the announced IPv4 prefix is Connor McFarlane of Inferno Communications Ltd, which differs from the AS holder Colocation Ltd, indicating a relationship between the two entities.
  • The address inventory is small, consisting of a single /24 IPv4 block and two IPv6 prefixes, all located in the United Kingdom.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
