Summary
Telekom Deutschland
mobile residential isp germany
ASN-TSI-IAS is operated by Telekom Deutschland GmbH.
What it's used for
- The address space carries mobile and fixed-line subscriber traffic, evidenced by netnames such as
DE-DETEMOBIL-20080304andDE-DETEMOBIL-20020910. - The AS announces 47,616 IPv4 addresses across 11 prefixes and 30 IPv6 prefixes, while maintaining only 4 observed routing neighbours. This high address-to-neighbour ratio indicates an access network rather than a transit provider.
- Traffic from this AS consists of end-user data from Deutsche Telekom's mobile and fixed-line subscribers in Germany.
Notable
- All registrants for the announced prefixes are listed as Telekom Deutschland GmbH, with administrative contacts assigned to T-Systems Business Services GmbH.
- The address inventory is dominated by large blocks in the 93.122.0.0/18 and 82.210.224.0/19 ranges, consistent with a major national carrier's mobile and broadband estate.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
