AS12507 announces 2 IPv4 prefixes covering 1,536 addresses and 0 IPv6 prefixes.

About this network

A network named for a company but registered to a person, holding two blocks with a gap between them.

What it's used for

• Internet access. 1,536 addresses in two IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is SWIFT-TRACE-AS, but both blocks are registered under netname RU-SERGIENKO to an individual, Nikita Sergienko.
• The two prefixes are 195.49.200.0/22 and 195.49.206.0/23 — parts of the same 195.49 space with 195.49.204.0/23 missing between them.
• Present in routing data since the collectors' earliest records in August 2000.

Interesting

• A company name on the AS and a person's name on every block is the normal shape of a small operator, where the individual who applied to the registry and the business that sells the service are the same concern wearing two hats. The registry records who signed; the AS name records who trades.
• The gap between the two blocks is the more useful detail. Contiguous space would suggest a single allocation later split; a /22 and a /23 with a /23-sized hole means these arrived separately, and whatever sits in the hole belongs to somebody else. Address space at this size is assembled from whatever the registry had free, not carved from one block.
