Summary
O2 Czech Republic
isp mobile eyeball backbone
O2 Czech Republic — a major Czech mobile and fixed operator and former national incumbent.
What it's used for
- Mobile data plus fixed broadband and IPTV for a large Czech subscriber base.
Notable
- A major "eyeball" network — addresses are a mix of mobile devices behind carrier-grade NAT and fixed home connections.
- Owned by the PPF group; its physical network was spun off into the separate infrastructure company CETIN.
Interesting
- Once part of Telefónica, the company kept the O2 brand after PPF acquired it, then separated ownership of the network layer from the retail operator.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
