AS12831 — TASK-AS

AS12831 announces 12 IPv4 prefixes covering 27,648 addresses and 1 IPv6 prefixes.

About this network

A university computing centre with 29 neighbours, carrying regional businesses on its own blocks.

What it's used for

• The academic computer centre of a Polish technical university, serving the region's research institutions. 27,648 addresses across twelve IPv4 prefixes, one IPv6 prefix, and 29 observed BGP neighbours.

Notable

• The largest blocks are 89.191.160.0/19 and 213.192.64.0/19, with 213.192.96.0/20 and 213.192.120.0/21 alongside.
• Three prefixes share the netname PL-TASK-20001024, registered to the technical university; 89.191.160.0/19 is PL-TASK-20060620.
• Two blocks belong to other organisations: 178.217.248.0/21 is PRO-SYSTEM, and 91.244.248.0/22 is PCPD2-NET, a regional data-processing centre.
• One of eighteen sampled addresses returned a name: 573eede3bb107.rev.snt.net.pl.

Interesting

• The one reverse name that answered is a hexadecimal string. Generated reverse zones usually encode the address in the hostname so an operator can read it; hashing it instead produces a unique name that tells you nothing, which is either a privacy choice or the shortest path to guaranteeing uniqueness.
• Three blocks stamped the same October 2000 date is one allocation recorded as three objects. The registry's dates record filing days, so identical dates across prefixes mark a single transaction rather than a pattern of growth.
• A university centre announcing a commercial systems house and a regional data centre is what academic networking looks like in practice. The research network was the only serious connectivity in the region for years, so it took on neighbours that were never academic, and the arrangement outlasted the reason for it.
