Summary
Deutsche Telekom
isp eyeball backbone
Deutsche Telekom's network (DTAG) — Germany's incumbent telecom, running the country's largest broadband and mobile access network.
What it's used for
- Consumer and business fixed broadband and mobile across Germany, plus a large national backbone.
Notable
- One of Europe's biggest "eyeball" networks by subscriber count.
- Parent of T-Mobile; the Deutsche Telekom group operates many national ASNs, with 3320 the German domestic core.
Interesting
- Deutsche Telekom's peering stance has periodically been contentious — as a huge eyeball network it has significant leverage in interconnection negotiations.

Classification and threat
Mobile Cellular carrier. Addresses are shared by many handsets via CGNAT.
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
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
31.232.221.35 | Chinese Government-linked Cyber Threat Actors Combine Automated and Hands-on Hacking Tools to Steal Sensitive Data | 2026-10-08 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
