About this network

Reverse names with the octets written backwards, under a domain belonging to a company since absorbed.

What it's used for

• A regional network of a Russian mobile and fixed-line operator, serving the Vologda area. 21,504 addresses across seven IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• Fourteen of 18 sampled addresses returned names of the form 0-104-65-176.vologda.comstar-r.ru for the address 176.65.104.0.
• Netnames are VOLOGDA-STREAM-NET, VOLOGDA20-STREAM-NET and RU-MTU-20120711.
• Two blocks still list a predecessor company as a registrant alongside the current operator.
• One prefix could not be looked up in the registry; the fetch failed.

Interesting

• The octets are written in reverse order, matching the layout of the reverse tree rather than the address itself. This is the second holder in this range to generate names that way, so it is a recognisable convention rather than a one-off mistake, and it means a name and its address read as mirror images.
• The domain belongs to a company that no longer exists independently, and its registry objects sit beside the acquirer's. Neither the zone nor the netnames were rewritten after the merger.
• One neighbour for 21,504 addresses is a regional arm reaching the internet entirely through its own parent's backbone.
