Summary

TDF

France · AI-generated

business media telecom france

TDF is the autonomous system for TDF SASU, a French telecommunications and media services provider.

What it's used for

  • The address space is registered under netnames such as FR-TDF-20081128 and FR-TDF-20031230, with registrants consistently listed as TDF SASU and TDF RIPE ADMIN.
  • The AS announces 31,488 IPv4 addresses across 12 prefixes and 4 IPv6 prefixes, while maintaining only 2 observed routing neighbours.
  • This high address-to-neighbour ratio indicates an internal corporate estate rather than a transit or access network, consistent with TDF's business of providing satellite transmissions, telecommunications, and multimedia services.

Notable

  • All registrant data aligns with the announcer, with TDF SASU and TDF RIPE ADMIN appearing across all sampled prefixes.
  • The address inventory is finely subdivided into 12 distinct IPv4 prefixes, reflecting site-by-site segmentation typical of a large corporate infrastructure.
  • One prefix, 95.81.175.0/24, carries the netname FR-Advalem, which differs from the standard TDF naming convention but remains registered to the same administrative entity.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
