About this network

A large technical university's network, with the faculties visible in its reverse DNS.

What it's used for

• Campus and research connectivity. 13,312 addresses in three IPv4 prefixes with twelve observed BGP neighbours and no IPv6 announced.

Notable

• All three blocks are adjacent parts of the same range — 194.29.128.0/19, 194.29.160.0/20 and 194.29.176.0/22 — announced separately rather than as one.
• All three share netname PW-NET, registered to Politechnika Warszawska.
• The two addresses that answered in the sample name their department: studnet-brcst.ii.pw.edu.pl and gateway.mini.pw.edu.pl.

Interesting

• ii and mini are faculties, and the reverse tree is delegated down to them. A university network is a federation more than a hierarchy: the central office holds the addresses and the peering, and each institute runs its own subdomain, its own gateway and, historically, its own argument about who gets which subnet.
• studnet-brcst names a broadcast address on the student network, which is the sort of record only a hand-maintained zone contains. Somebody documented the top of the range so that whoever met it in a log would know what they were looking at.
