Summary
Warsaw University of Technology
education university research
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 —
194.29.128.0/19,194.29.160.0/20and194.29.176.0/22— 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.plandgateway.mini.pw.edu.pl.
Interesting
iiandminiare 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-brcstnames 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.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
