Unclassified RIPE Cable/DSL/ISP
Summary
C2 Internet
isp business hosting
Seven prefixes carrying one February 2000 date, and eighteen addresses that answer nothing.
What it's used for
- A United Kingdom business internet provider. 5,376 addresses across 12 IPv4 prefixes, one IPv6 prefix, and two observed BGP neighbours.
Notable
- Seven of the sampled blocks carry the identical netname
UK-C2INTERNET-20000216; a later one isUK-C2INTERNET-20050208. - Every block is registered to Atlas Business Group Companies Ltd, while the netnames and the AS handle say C2INTERNET.
- The AS handle is the trading name followed by the full legal company name.
- Eighteen addresses were sampled and none answered.
Interesting
- One date across seven separate announcements is a single allocation split for routing, not seven acquisitions made to land on the same day. The netname records when the paperwork cleared, so every fragment inherits it however long afterwards the fragment was announced.
- Trading name and registrant have diverged. The brand is what customers were sold and what got typed into the netname field; the legal entity is what holds it now. Neither field updates when the other changes, so the pair is a rough record of a company's history.
- Two neighbours for 5,376 addresses is a provider buying transit rather than peering, the ordinary shape for an ISP selling connectivity rather than reach.
- Nothing answered across eighteen addresses. Providers aimed at business customers often leave reverse records for the customer to request, and customers rarely do.

Reputation
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 1,773 prefixes, as published 2026-10-13. 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.
