Summary
TeleData
residential isp germany fttx
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.deandstatic-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 byStadtwerke Engen GmbHandStadtwerke 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.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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.
