Summary

Województwo Warmińsko-Mazurskie

Poland · AI-generated

government administrative poland

The AS handle UMWWM-AS is held by Województwo Warmińsko-Mazurskie, the administrative region of Warmian-Masurian Voivodeship in Poland.

What it's used for

  • The space carries a single IPv4 prefix, 213.73.31.0/24, with the netname UMWWM and registrant abuse OLMAN.
  • The inventory consists of 256 IPv4 addresses across 1 prefix, with 0 IPv6 prefixes announced.
  • With only 2 observed neighbours, the low neighbour count relative to the address space suggests a limited connectivity footprint typical of a specific institutional or administrative network rather than a transit provider.

Notable

  • The registrant abuse OLMAN for the prefix 213.73.31.0/24 differs from the AS holder name, indicating potential historical registration or specific abuse contact designation.
  • The address inventory is minimal, consisting of a single /24 block, which aligns with the needs of a regional government administrative body rather than a large-scale ISP or hosting provider.

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.
