Summary
Cosmote / OTE
isp mobile eyeball backbone
Cosmote — the mobile brand of OTE, Greece's incumbent telecom operator, which is part of the Deutsche Telekom group. It is the largest mobile network in Greece.
What it's used for
- Mobile data and voice nationwide, alongside OTE's fixed broadband; the group markets converged fixed-plus-mobile services under the Cosmote brand.
Notable
- A large consumer "eyeball" network for mobile users, often behind carrier-grade NAT; as the national incumbent, OTE also carries significant transit/backbone traffic in Greece.
- Backed by Deutsche Telekom, which controls the OTE group.
Interesting
- OTE consolidated its consumer offering under a single Cosmote brand for both fixed and mobile, a common convergence move among European incumbents.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
