About this network

TELEDATA-AS is operated by TeleData GmbH, a regional telecommunications provider based in Friedrichshafen.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries such as host-212-62-215-254.teledata-fttx.de and static-81-27-123-254.teledata-fttx.de, indicating fiber-to-the-x and static IP services.
• With 50,432 IPv4 addresses announced across 39 prefixes and 166 observed neighbours, the high neighbour count relative to the address inventory suggests a role focused on peering and transit exchange rather than pure transit provision, consistent with a regional access network.

Notable

• Registrants largely align with the announcer, with most prefixes registered to TeleData GmbH; TeleData ISP-Team, though some blocks are held by Stadtwerke Engen GmbH and Stadtwerke Tuebingen GmbH, indicating leased space or municipal partnerships.
• The address inventory is finely subdivided into numerous /20, /21, and /22 blocks, reflecting a segmented internal estate for different service areas or customer segments.
