government municipal russia sakhalin

YUZHNOSAKHALINSK-AS is operated by MKU "Digital Transformation of the City Administration of Yuzhno-Sakhalinsk".

What it's used for

  • The space carries municipal government infrastructure, as indicated by the registrant Upravlenie delami administratsii goroda Yuzhno-Sakhalinska; MKU "Digital Transformation of the City Administration of Yuzhno-Sakhalinsk" and netname ORG-MTOT1-RIPE.
  • The AS announces a single IPv4 prefix, 213.5.73.0/24 (256 addresses), with 0 IPv6 prefixes and 2 observed neighbours.
  • Traffic from this AS consists of internal administrative and digital services for the city government of Yuzhno-Sakhalinsk, the capital of Sakhalin Oblast.

Notable

  • The RDAP registrant matches the AS holder, confirming the space is directly owned by the municipal entity.
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a small municipal network rather than a large ISP or transit 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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
