Poland · AI-generated

government municipal poland

The AS handle UMSOPOT is held by Urząd Miasta Sopotu.

What it's used for

  • The address space carries municipal government operations, as indicated by the netname UMSOPOT and registrant Urzad Miasta Sopotu.
  • The network announces 512 IPv4 addresses within a single prefix (91.195.108.0/23) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications and services for the City of Sopot administration.

Notable

  • The RDAP registrant Urzad Miasta Sopotu aligns with the AS holder, confirming the space is owned and operated by the municipal government.
  • The inventory consists of a single contiguous /23 block, typical for a dedicated institutional allocation.

Reputation

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
