AS13105 announces 9 IPv4 prefixes covering 23,552 addresses and 0 IPv6 prefixes.

About this network

Twenty-seven prefixes for 23,552 addresses, and a registrant field containing the word Administrative.

What it's used for

• The IT subsidiary of a Russian oil company. 23,552 addresses across 27 IPv4 prefixes, 11 observed BGP neighbours, and no IPv6 announced.

Notable

• Every block carries an RU-RTK-INFORM netname, dated 19990826, 20040213 or 20090225.
• Every registrant list begins with the bare word Administrative.
• The handle names the parent oil company; the holder field names only the subsidiary; the netnames name a third company again.
• Eighteen addresses were sampled and none returned a name.

Interesting

• An eight-digit date from 1999 appears here on a block registered years before the shorter form shows up elsewhere in this range. Whatever governed the choice between six and eight digits, it was not the calendar.
• Administrative standing alone as a contact is a role object whose name is the word for its own function. It identifies nobody, and it is the fourth variation in this range on the same theme: a registrant field filled with a job description instead of a party.
• Twenty-seven prefixes averaging under 900 addresses each, for a corporate network with 11 neighbours, is space accumulated site by site across a country. Each field office needed a block and each block became its own announcement.
