AS15638 announces 8 IPv4 prefixes covering 9,216 addresses and 0 IPv6 prefixes.

About this network

Nine thousand addresses across eight routes, all behind one observed neighbour.

What it's used for

• A regional provider. Eight IPv4 prefixes announced from the Russian Federation, no IPv6, nine thousand addresses, through one observed BGP neighbour.

Notable

• One neighbour carries everything, so eight routes and three separate ranges all leave by the same door.
• Six blocks share a netname built from the AS handle's three-letter code with a network suffix and no date; one uses the country code with the trading brand and a date; one is written with underscores instead of hyphens.
• The AS handle continues past that code into a town name.
• The holder name and the netnames use two different brands for the same operator, and the contact roles mix both.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• Routing records first show this number some years after the ones around it appeared.

Interesting

• Underscores in a netname are legal and almost never used. One appearing in a single block means that record was created outside whatever process produced the other seven.
• A town in the AS handle places the network more precisely than any other field here, which matters for an operator whose addresses come from three unrelated ranges.
• Eight routes through one upstream means the split serves internal purposes only. From outside, the whole network has exactly one way in.
