Summary
Cosmote Mobile Telecommunications S.A.
mobile residential telecom greece
The AS handle COSMOTE-GR is held by Cosmote Mobile Telecommunications S.A., a subsidiary of Ote SA (Hellenic Telecommunications Organisation).
What it's used for
- The address space carries mobile and residential traffic, evidenced by reverse DNS entries such as
nat64.nym.cosmote.net,pat.amp.cosmote.net, andmobile.nym.cosmote.net. - The AS announces 247,552 IPv4 addresses across 11 prefixes and 10 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.
Notable
- All RDAP registrants for the largest prefixes are listed as OTE IP ADM; Ote SA (Hellenic Telecommunications Organisation), which aligns with the parent company structure of the announcer.
- The address inventory consists of several large /16 blocks (5.203.0.0/16, 31.152.0.0/16, 109.178.0.0/16) alongside smaller /24 and /23 allocations, reflecting a mix of legacy and modern mobile spectrum assignments.

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 1,779 prefixes, as published 2026-10-22. 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.
