AS47638
The autonomous system of Cadence Networks - an independent UK ISP. Our own IPv4 and IPv6 space, Juniper MX & ACX metal, public peering at LINX and LONAP, and private interconnects with the networks our customers actually talk to.
We peer. You should peer with us.
Peering requests are welcome - our ports, prefixes and contacts live on PeeringDB, and that's the fastest way to get a session up.
