AS13786 — SEABORN

AS13786 announces 2 IPv4 prefixes covering 3,072 addresses and 2 IPv6 prefixes.

About this network

641 neighbours against two IPv4 prefixes, and a netname that is nothing but a six-digit number.

What it's used for

• A submarine cable operator's network. 3,072 addresses across two IPv4 prefixes, 27 IPv6 prefixes, and 641 observed BGP neighbours.

Notable

• The neighbour count is the highest in this range by a wide margin, from one of the smallest IPv4 footprints.
• 45.177.100.0/22 is netname 359764, a bare number, registered to the group's Brasil company.
• 207.135.208.0/21 is netname SEABORN-V4 and belongs to the American one.
• Eight consecutive /39s under 2605:4a40 tile a single /36 exactly, while the /36 beside them is announced whole.
• Five of six sampled addresses answered, all hyphenated under one domain.

Interesting

• Six hundred neighbours is not a customer count, it is an interconnection count. A cable operator sells capacity between two continents, so its value is measured in who it touches rather than in how many addresses it holds. Two prefixes and 641 adjacencies is that business written in routing data.
• One block from each of two registries, held by two national companies of the same group, is what a cable landing at both ends requires: address space that is local wherever the equipment sits.
• Splitting one /36 into eight equal pieces while announcing its neighbour as a single route is two policies applied to identical amounts of space.
