Unclassified RIPE
Summary
BT Ignite Content Hosting
hosting telecom enterprise
A hosting registry from a retired brand still holds every block, and two of them name nobody at all.
What it's used for
- A content hosting network of a large telecommunications company in the United Kingdom. 17,664 addresses across eight IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.
Notable
- Six blocks list
Ignite Content Hosting Registryfirst, ahead of the operating company and a corporate registry contact. 137.213.252.0/23and137.213.239.0/24are netnameSTERIAUKwith the registrant recorded as unknown.- The AS handle is
BTWWIDC-H Autonomous System. - Eighteen addresses were sampled and none returned a name.
Interesting
- Three contacts on one block, in order of decreasing specificity, is a large organisation's answer to the question of who owns an address: the hosting arm, the legal entity, and the group registry that arbitrates between them. Each was added by someone solving a different problem.
- Two blocks carry a netname from an entirely separate services company with no registrant recorded. The lookup returned a record and the record names no party, which is different from a lookup that failed, and it means the trail ends there.
- Space adjacent to some of these prefixes, in the same range, is announced from another country by an unrelated operator elsewhere in this sweep. Neighbouring addresses have separate owners here.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, 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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
