About this network

Three company names in one record: one in the handle, one in the holder, one in the netname.

What it's used for

• A Russian network operated by a national telecommunications group. 8,192 addresses in one IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is CTK-NET-AS; the holder is a different company again; the netname is RU-SOVINTEL-20000316, a third.
• The same third name appears twice more, in the network operations and abuse contacts.
• The single prefix is 213.150.64.0/19.
• Three addresses were sampled and none returned a name.

Interesting

• Three names is a merger chain written into three fields that update at different rates. The netname and its contacts are the oldest and have never been touched; the holder field was rewritten when the company changed hands; the handle preserves whatever the network called itself when the number was issued. Read together they give the sequence of ownership that no single field records.
• The netname date sits within weeks of the block being registered, and the operator whose name it carries has not existed independently for many years. Netnames are effectively permanent, which makes them the most reliable dating evidence in the registry and the least reliable ownership evidence.
• A single /19 behind one neighbour is a regional piece of a much larger network, reachable only through its own parent.
