AS8838 STRIPE-21-GROUP-LIMITED Stripe21 - Business Telecoms Solutions - www.stripe21.com

STRIPE-21-GROUP-LIMITED is held by Compuweb Communications Services Limited — better known as CWCS, a Nottingham managed-hosting provider — which acquired Stripe 21, a Dorking-based business telecoms company, to bolt connectivity and voice onto its hosting portfolio. The AS carries the Stripe21 name and the Stripe21 network.

What it's used for

Business connectivity and voice: leased lines, FTTP and SoGEA business broadband, SIP trunks and hosted VoIP, sold to UK companies, plus CWCS's managed hosting behind it. The one PTR returned in the sample is telling on its own — lo0.asr9k01.ld8.stripe21.net is the loopback interface of a Cisco ASR 9000 edge router sited in LD8, Telehouse North in London Docklands. That is a carrier-grade router in the country's densest interconnect building, which is where a small B2B provider puts its edge if it means to peer seriously.

Notable

• Two prefixes — 212.42.0.0/19 and 194.50.108.0/24, about 8,400 addresses — plus IPv6. Small, contiguous, self-registered.
• 32 observed BGP neighbours against only 8,400 addresses. The neighbour-to-address ratio is the real signal here: this network peers far more widely than its size would suggest, consistent with a Docklands-based provider that peers at LINX rather than buying a single transit pipe.
• No subscriber-pool naming in the sample. Everything points at business customers and hosted services rather than an eyeball network.

Interesting

The ld8 in the router name is not a hostname convention the company invented — it is the industry shorthand for Telehouse North, and it shows up in the reverse DNS of dozens of unrelated UK networks for the same reason.
