AS13809 — UAMS-ASN

AS13809 announces 7 IPv4 prefixes covering 130,048 addresses and 0 IPv6 prefixes.

About this network

Twenty-one prefixes and the largest academic address count in this range, all one netname, behind a single upstream.

What it's used for

• A medical university and hospital system's network. 130,048 addresses across 21 IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The prefixes divide two parent ranges into pieces from a /17 down to a /23.
• Every readable one is netname UAMSNET, registered to the university.
• One neighbour carries all of it.
• One of the twelve sampled blocks failed to return a registry record.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• This is the largest address count of any academic network in this range, and it sits behind one upstream. Four universities here hold between sixty-five and a hundred and thirty thousand addresses and three of them route through a single provider, which says the AS number is about holding space rather than about surviving a failure.
• Splitting two parents into twenty-one announcements while labelling every piece identically is deaggregation for internal reasons that the registry does not record. A reader sees twenty-one routes and one organisation.
• A teaching hospital's network carries clinical systems as well as academic ones, which makes the single upstream the most interesting number in the record.
