About this network

Five brand names for one network, spread across the holder field, the handle, the netnames and the DNS.

What it's used for

• A regional access network in Murmansk. 14,336 addresses across three IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The registry holder is a national mobile operator; the AS handle is POLARCOM-AS Murmansk.
• All three netnames use a fourth name: RU-SOVINTEL-20000427, RU-SOVINTEL-20070502 and RU-SOVINTEL-20100416.
• Sampled names are hsrp-int.mtf.ru and 77-245-203-254.polarnet.ru, two more domains again.
• One observed neighbour against 14,336 addresses.

Interesting

• Every layer of this record preserves a different era's name. The registry knows the current parent, the AS handle keeps the regional operator, the netnames keep the company that received the allocations, and the DNS keeps two more. None of them was wrong when it was written, and nothing ever goes back to reconcile them.
• The eight-digit netname dates run from 2000 to 2010 under a brand that the parent company no longer uses, so the label outlived the business it named by at least the length of that span.
• One of the two published names is a router interface serving a redundancy protocol rather than a customer address. Somebody named the machine for its job, and that name is now the only public description of that address.
• A single neighbour for a network this size means the archive sees one way in and out.
