AS16301 DATACOM-AS Novgorod Datacom LLC

Eight opaque letters carrying the registry's own role suffixes, listed on half the blocks.

What it's used for

• A carrier's regional network. Eighteen IPv4 prefixes announced from the Russian Federation, no IPv6, seventy-eight thousand five hundred and ninety-two addresses, through one observed BGP neighbour.

Notable

• Two netname schemes split the blocks. Four use a country code, three letters for the carrier, and a full date. Seven use a regional brand and the word for a network, with no date at all.
• Several blocks list two roles whose labels are the same eight-letter string followed by the registry's internal names for administrative and technical contacts. The database's own field names are showing through into the human-readable record.
• Those eight letters appear in no other field and expand to nothing the record explains.
• The blocks with the regional brand list only the carrier's technical team, while the dated blocks list four contacts each.
• The AS handle is the regional brand, the letters for an autonomous system, and then a city with the brand and a legal suffix, which is the only place the operator's own name appears in full.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Role handles that leak the registry's schema are a sign of records created by tooling rather than by hand. Somebody scripted the contact objects and named them after the field they fill.
• Seventy-eight thousand addresses behind one observed upstream is a regional network that reaches the rest of the internet entirely through its parent.
