AS13215 — CPLUS1-AS

Network type: residential

AS13215 announces 3 IPv4 prefixes covering 1,536 addresses and 19 IPv6 prefixes.

About this network

Thirty IPv6 announcements against three IPv4 prefixes, doubling in size at every step.

What it's used for

• A telecommunications company in the Russian Federation. 1,536 addresses across three IPv4 prefixes, thirty IPv6 prefixes, and 23 observed BGP neighbours.

Notable

• The IPv6 list runs 2a0b:a8c0:4::/46, 8::/45, 10::/44, 20::/43, 40::/42, 80::/41, 100::/40, 200::/39, each twice the previous.
• IPv4 is 185.97.164.0/22 plus two /24s, netnames RU-CONVEYPLUS-20150423 and CONVEYPLUS.
• Two blocks list Abuse OBL as the only contact.
• Nine addresses were sampled and none returned a name.

Interesting

• Ten times as many IPv6 announcements as IPv4 ones, on a network with 1,536 IPv4 addresses. The cascade of doubling prefix sizes is a range splitter covering an interval whose edges do not land on a single boundary, and each piece costs everyone else a routing table entry.
• This is now a recurring shape across this range rather than one operator's quirk. The same arithmetic signature appears wherever an operator announces a sub-range of its own allocation through tooling instead of by hand.
• 23 neighbours on a small network is peering-led connectivity, and the mismatch between that and the address count is the usual sign of a business selling paths rather than space.
