Summary

Régie des Transports Métropolitains

France · AI-generated

transport municipal business france

RTM-AS is held by Régie des Transports Métropolitains.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname FR-RTM-20180516 and registrant REGIE DES TRANSPORTS METROPOLITAINS.
  • The AS announces 768 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal systems for the municipal transport authority based in Marseille.

Notable

  • Registrants agree with the announcer, with both prefixes registered to REGIE DES TRANSPORTS METROPOLITAINS.
  • The address inventory consists of two contiguous IPv4 blocks: 194.36.116.0/23 and 194.36.118.0/24.

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.
