AS14763 — STKATE

AS14763 announces 3 IPv4 prefixes covering 16,640 addresses and 0 IPv6 prefixes.

About this network

Two /19s from one range with a quarter of it missing in between, and a /24 whose netname bothers to say it is IPv4.

What it's used for

• A university campus network. 16,640 addresses across three IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

• 140.225.0.0/19 and 140.225.128.0/19 both carry the netname STKATE-NET, registered to St. Catherine University.
• The third block is 23.138.116.0/24, netname STKATE-IPV4-24.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• The two /19s are not adjacent. They sit at the start and the midpoint of the same range, which means the space between them is either used without being announced or belongs to somebody else entirely. A shared allocation split between institutions leaves exactly this fingerprint.
• Writing IPV4 into a netname is only worth doing once both protocols exist and the distinction can be ambiguous. The two older blocks predate the question and say nothing about it, so the netnames date themselves.
• That third block also comes from a range issued long after the first two, in /24 units, which is what an institution buys or is allocated once the easy space is gone. Two /19s from the old world and one /24 from the new.
• Three neighbours on three prefixes is better redundancy than most campuses in this range manage, and announcing no IPv6 at all is the more surprising half of the record.
