AS13094 announces 1 IPv4 prefixes covering 512 addresses and 0 IPv6 prefixes.

About this network

Hostnames built with underscores, which are not valid characters in a hostname.

What it's used for

• A Russian internet exchange point. 512 addresses in one IPv4 prefix, 70 observed BGP neighbours, and no IPv6 announced.

Notable

• Two of three sampled addresses returned names: host91221180128.milecom.ru and host91221181126.milecom.ru.
• The netname is SFO-IX; the registrant is a company named in neither the handle nor the holder field.
• Seventy observed BGP neighbours behind a single /23.
• First observed in the routing archive in October 2001.

Interesting

• Underscores separate the octets where every other generated name in this range uses hyphens. The hyphen convention is not a style choice: underscores are outside the character set hostnames are defined over, and strict resolvers and some client libraries reject them. These names work in practice because most software is lenient, which is exactly why the mistake survives.
• Seventy neighbours against 512 addresses is the clearest exchange-point signature there is. The space is the shared fabric that member networks peer across; the traffic never terminates here, so the address count says nothing about the volume.
• Four different organisation names appear across the handle, the holder, the registrant and the reverse zone. Exchange points are often run by one company on another's infrastructure, and every layer keeps its own.
