AS13119 announces 23 IPv4 prefixes covering 9,984 addresses and 1 IPv6 prefixes.

About this network

A university computing centre whose address space answers under two commercial domains.

What it's used for

• The academic computing centre of a Polish technical university. 9,984 addresses across 23 IPv4 prefixes, one IPv6 prefix, and 41 observed BGP neighbours.

Notable

• Netnames are mostly PL-AMSK, dated 980223, 20010423 and 20050727.
• One is TarninyplMaciejPrazucha, joining a domain and an individual's name with underscores.
• Five of 18 sampled addresses returned names under tarniny.pl and static.dobrynet.eu, neither belonging to the university.
• The IPv6 announcement is a /30, larger than the standard allocation size.
• Two prefixes could not be looked up in the registry; the fetches failed.

Interesting

• A netname built from a domain plus a person's name is the registry being used as a customer database. Whoever assigned that block wrote down who got it in the only field available, and it has been public ever since. The matching domain then turns up in the reverse zone, confirming the assignment years later.
• Twenty-three prefixes for under ten thousand addresses, most of them /23s and /24s carved from three parent ranges, is space handed out per customer and announced per customer.
• University computing centres in this period were the only organisations in many cities with transit, so they sold it. Forty-one neighbours is not an academic figure; it is a regional provider's.
