Summary

UMS Gmina Miasto Szczecin

Poland · AI-generated

municipal government network poland

The AS handle UMS is held by UMS Gmina Miasto Szczecin, the municipal government of Szczecin.

What it's used for

  • The address space carries municipal network infrastructure, evidenced by reverse DNS entries pointing to um.szczecin.pl and netnames ums and ums2.
  • The network announces 768 IPv4 addresses across 2 prefixes and maintains 3 observed neighbours, a ratio consistent with a small-scale internal or municipal access network rather than a transit provider.
  • Traffic from this AS consists of internal municipal services and administrative endpoints for the city of Szczecin.

Notable

  • Registrants for both announced prefixes are listed as "Abuse Contact" with netnames ums and ums2, aligning with the registry holder UMS Gmina Miasto Szczecin.
  • The address inventory is compact, consisting of a /23 and a /24 block, with no IPv6 prefixes announced.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
