AS8801 AS-ROCKET United Kingdom

ROCKETFIBRE (the worklist handle still reads AS-ROCKET United Kingdom) is Rocket Fibre Ltd, a UK network that today sells DDoS-protected IP transit and wholesale carrier capacity, with routing nodes at Telehouse North and Equinix LD8 in London.

What it's used for

The tell is in the peering, not the address count. Rocket Fibre announces only ~9,700 IPv4 addresses across seven prefixes, but shows 227 observed BGP neighbours. That ratio — a small address holding behind a very large peer count — is the signature of a transit and peering business rather than an eyeball network. The company markets IP transit commits from 10 Mbit up to 10 Gbit and peers with the major UK networks.

Sampled reverse DNS across 83.167.184.0/22 returns generic first-party naming of the form ip-A-B-C-D.rocket-fibre.co.uk — operator-assigned addresses with no dsl, pppoe, dyn or pool markers to indicate a consumer subscriber base.

Notable

• The company has a broadband history it has been shedding: it ran a legacy UK fixed-wireless broadband service and moved in 2025 to disconnect those remaining users. The AS's centre of gravity is now wholesale transit, so classifying it from the "Fibre" name as a retail ISP would describe the past, not the present.
• The address inventory mixes UK RIPE space (83.167.0.0 blocks) with 154.x and 193.56.176.0/22 assignments, consistent with a network accumulating blocks over a long life rather than a single clean allocation.
