About this network

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.
