Summary

Gmina Miasta Jaworzna

Poland · AI-generated

government municipal poland

UMJ-MSS-AS is operated by Gmina Miasta Jaworzna, the municipal government of Jaworzno.

What it's used for

  • The address space carries municipal infrastructure, evidenced by the netname PL-GMINAJAWORZNO-20130828 and registrant Gmina Miasta Jaworzna.
  • The AS announces 1024 IPv4 addresses within a single prefix (185.34.28.0/22) and has 1 observed neighbour, indicating a small, self-contained network with no transit role.
  • Traffic from this AS consists of internal municipal services and administrative endpoints for the city of Jaworzno.

Notable

  • The RDAP registrant Gmina Miasta Jaworzna matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous /22 block, typical for a municipal network requiring a modest, stable address range.

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 1,854 prefixes, as published 2026-11-06. 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.
