AS49013 FUSION_MEDIA
Unclassified RIPE
Summary
Fusion Media, s.r.o.
business czech media
FUSION_MEDIA is operated by Fusion Media, s.r.o.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by reverse DNS entries pointing to
corelabs.cz(e.g.,unn-188-240-1-64.corelabs.cz). - The AS announces 1280 IPv4 addresses across 2 prefixes while maintaining 23 observed neighbours, a ratio consistent with a business network requiring transit connectivity rather than an access provider.
- Traffic from this AS represents office workers and internal services for a Prague-based media company, not subscriber eyeballs or public hosting endpoints.
Notable
- Registrants for both announced prefixes (
CZ-FUSION-20160215andCZ-FUSION-20090623) align with the AS holder, Fusion Media, s.r.o. - The address inventory is small and subdivided into two distinct blocks, reflecting an internal corporate estate rather than a large-scale service provider footprint.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
