Ukraine · AI-generated

education university ukraine

PU-AS is the autonomous system for Precarpathian National University of Vasyl Stefanyk, a public higher education institution in Ivano-Frankivsk, Ukraine.

What it's used for

  • The space carries university infrastructure, indicated by the netname ICPU associated with the single announced prefix.
  • The AS announces 256 IPv4 addresses within one prefix (194.44.152.0/24) and has 0 IPv6 prefixes. With only 1 observed neighbour, this ratio indicates a small, isolated access network typical of an institutional campus rather than a transit provider.

Notable

  • The RDAP registrant for the prefix is listed as Abuse-C Role, which is a generic abuse contact designation rather than a distinct corporate entity, consistent with the university's direct ownership.
  • The address inventory consists of a single /24 block, representing a compact and self-contained estate for the university's internal network needs.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
