Summary
Warner Bros. Discovery
media content enterprise czechia
WBD-AS is the autonomous system for Warner Bros. Discovery, operated through its Czech entity HBO Europe s.r.o.
What it's used for
- The address space carries corporate and content delivery infrastructure, evidenced by netnames
WBD-157-166,WBD, andCZ-HBOEUROPE-20220228, with registrants including Turner Broadcasting System, Inc. and Warner Bros. Discovery. - The AS announces 2048 IPv4 addresses and 5 IPv6 prefixes across 4 IPv4 and 9 total prefixes, while maintaining 47 observed neighbours, indicating a role focused on content distribution and peering rather than residential access.
- Traffic from this AS consists of web and API endpoints for streaming services, media content delivery, and internal corporate backhaul for Warner Bros. Discovery's global operations.
Notable
- Registrants align with the announcer, listing Turner Broadcasting System, Inc. for legacy prefixes and Warner Bros. Discovery or HBO Europe s.r.o. for current holdings.
- The address inventory is finely subdivided into small /24 and /23 blocks, reflecting an internal corporate estate segmented by function or site rather than a large consumer base.
- The AS was first seen in routing tables in 2007, predating the recent corporate mergers that formed Warner Bros. Discovery.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
