AS15191 — WIN-NET

AS15191 announces 2 IPv4 prefixes covering 5,120 addresses and 1 IPv6 prefixes.

About this network

Two equal blocks of space, one announced as a single route and one as four.

What it's used for

• A regional carrier's network. Six IPv4 prefixes and one IPv6 prefix announced from the United States, with eleven observed BGP neighbours.

Notable

• 198.29.32.0/21 is announced as one route, while the adjacent range of the same size is announced as four separate /23 routes that sit end to end with no gap.
• Both halves carry the same netname and the same registrant, so nothing in the registry distinguishes them.
• One further block uses a shortened netname with a counter instead, the only variation in the record.
• Sixteen of eighteen sampled addresses answered, all writing the address into the host label with hyphens under one domain.
• Several of those answers are for addresses ending in two hundred and fifty-five, which are broadcast addresses of their blocks and belong to no host.

Interesting

• The same operator made two opposite choices about the same amount of space. Four routes where one would do is the common outcome when blocks arrive separately and the configuration is never revisited; the single aggregate next door proves the operator knows how.
• A reverse zone that answers for broadcast addresses was generated for the entire block, so a name here confirms only that the block is delegated. It says nothing about whether an address is in use.
• Eleven upstreams for five thousand addresses is a carrier's profile, not a customer's.
