AS14598 — YCP-ASN

AS14598 announces 3 IPv4 prefixes covering 768 addresses and 1 IPv6 prefixes.

About this network

The one address that answered names a building alarm system.

What it's used for

• A college campus network. 768 IPv4 addresses across three prefixes, one large IPv6 allocation, and two observed BGP neighbours.

Notable

• 192.245.87.127 answers as springettsbury.alarm.ycp.edu, naming a place and a system in the same hostname.
• The three blocks carry three different netnames: COGENT-A, held by the provider, YORK-COLLEGE-OF-PENNSYLVANIA spelled out in full, and YCPA reduced to initials.
• The IPv6 announcement is 2602:f907::/36, far larger than the IPv4 footprint.
• Nine addresses were queried for reverse DNS and one returned a name.

Interesting

• Publishing a hostname that says alarm, with the site it protects as the first label, tells anyone scanning which address to look at first and what it does. It costs nothing to name that host something opaque, and campus networks are full of names like this because the person who set it up needed to find it again.
• Three netnames for one institution is a record of how it bought connectivity over time: a block in the carrier's name, a block filed with the college name written out by someone who had room, and an older one abbreviated to four letters by someone who did not.
• The IPv6 allocation dwarfs everything else here, which is normal for education. Universities were early recipients of large ranges and mostly still have them.
• Two upstreams for a campus is standard, and the smaller half of the arrangement is usually a research network rather than a commercial one.
