Summary
Rzeszow University of Technology
education academic poland
RMSK-COMM is the autonomous system for Rzeszow University of Technology.
What it's used for
- The address space is registered under the netname
PL-ACADEMIC-20060518with the registrant listed as Rzeszow University of Technology. - The AS announces a single IPv4 prefix,
89.188.192.0/22, comprising 1024 addresses, and maintains 2 observed routing neighbours. - As a state-run institution of higher education, the network carries traffic for academic research, administrative operations, and student access within the university's infrastructure.
Notable
- The RDAP registrant for the announced prefix matches the AS holder, confirming the space is directly owned by the university.
- The inventory consists of a single contiguous /22 block, indicating a consolidated internal corporate estate rather than a fragmented or leased address space.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
