Summary

O2 Czech Republic

Czechia · AI-generated

mobile residential isp telecom

The AS handle INTERNETPB-AS is held by O2 Czech Republic, a.s.

What it's used for

  • The address space carries mobile and fixed broadband traffic, as indicated by the registrant O2 Czech Republic, a.s. and netnames CZ-CZNET-20090904 and CZ-CZNET-20180515.
  • The AS announces 5120 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, a ratio characteristic of an access network serving end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs, including mobile data, fixed internet, and television services for customers in the Czech Republic.

Notable

  • Registrants for both announced prefixes are O2 Czech Republic, a.s., consistent with the AS holder.
  • O2 Czech Republic is a subsidiary of Telefónica, which acquired the Czech operations and rebranded them under the O2 name.
  • The inventory consists of two distinct IPv4 blocks, 109.72.0.0/20 and 194.31.216.0/22, alongside a single /32 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
