AS13005 — C2INTERNET Atlas Business Group of Companies Ltd
AS13005 announces 12 IPv4 prefixes covering 5,376 addresses and 1 IPv6 prefixes.
About this network
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 is UK-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.
