Summary

Moscow Mayor's Office (GKU Mosgortelecom)

Russia · AI-generated

government legacy

AS8901 is held by GKU "Mosgortelecom" — a gosudarstvennoye kazyonnoye uchrezhdeniye, a state institution of the City of Moscow — and is widely labelled the Moscow Mayor's Office network. It carries the municipal government's Internet presence.

What it's used for

  • Public-facing and administrative networking for Moscow's city government: the mos.ru estate and the departments behind it. Sampled rDNS returns ns1.mos.ru, and the abuse contact is noc@mos.ru.
  • This is government infrastructure, not a commercial ISP. There are no subscriber pools in the inventory.

Notable

  • About 8.4k IPv4 addresses across roughly 33 prefixes, mostly /24s carved from a legacy 212.11.128.0/19 plus 185.173.0.0/22 and a few strays.
  • Only a handful of observed BGP neighbours, and the upstreams are the Russian incumbents (Rostelecom, MegaFon, Comcor) — a consumer of transit, not a provider.

Interesting

  • The AS number dates from 1998, making the Moscow city administration one of the earlier municipal governments anywhere to run its own autonomous system rather than sit behind a telco.
  • An address here should be read as city-government infrastructure — a poor geolocation target for anything user-facing, since the residents of Moscow are not on this network.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
