Summary
University of Warmia and Mazury
education university olsztyn
OLMAN-COM-AS is operated by University of Warmia and Mazury in Olsztyn, Poland.
What it's used for
- The address space carries university infrastructure, evidenced by the registrant name and a reverse DNS entry pointing to
lab5.lab-mlek.com.pl. - With 3584 IPv4 addresses announced across 5 prefixes and only 6 observed neighbours, the ratio indicates an access or eyeball network serving the institution's campus rather than a transit provider.
Notable
- All registrants for the announced prefixes align with the announcer, listing the University of Warmia and Mazury in Olsztyn, Poland, with netnames such as
PL-OLMAN-20030704andPL-OLMAN-991210. - The inventory consists of five IPv4 prefixes, including two /22 blocks and two /24 blocks within the 213.73.0.0/16 range, plus one /22 in 213.184.0.0/16, with no IPv6 prefixes announced.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
2 upstream, 4 downstream and 6 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-17. 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.
