About this network

223,744 addresses reached through six neighbours, every one of them a cable modem.

What it's used for

• A Spanish cable operator providing internet to homes and businesses. 223,744 addresses across 28 IPv4 prefixes, three IPv6 prefixes, and six observed BGP neighbours.

Notable

• The large blocks are three /17s and four /18s.
• Netnames are either ES-CABLEGALICIA- with dates 20031219, 20041020 and 20080425, or the bare label TELECABLE.
• Six of eighteen sampled addresses returned names, all beginning cm-, in two forms: cm-83-97-223-254.telecable.es and cm-staticip-85-152-223-254.telecable.es.
• The AS handle is TELECABLE Spain.

Interesting

• Six neighbours for a network of this size is remarkably few. A cable operator's traffic is almost entirely inbound to subscribers, so a handful of large transit relationships carries everything, and there is little reason to peer widely when nobody is trying to reach you.
• cm is the cable modem, and it appears on every address that answers. The reverse zone is generated straight from the access network's equipment inventory, which is why the names are uniform in a way that a mixed hosting network's never are.
• The staticip variant marks subscribers paying for a fixed address, distinguishing them in the hostname itself. This is the same public sorting of customer classes that other operators do, and it exists because the systems on the receiving end treat the two differently.
• The dated netnames all name a regional cable company absorbed into this one, and the newer blocks dropped the name entirely rather than adopting a new prefix.
