What it's used for
- The address space carries corporate infrastructure for a major Czech publishing house, as indicated by the netname
VLP-NETand registrantVLTAVA LABE MEDIA a.s. - The AS announces 512 IPv4 addresses within a single /23 prefix and 1 IPv6 /48 prefix, while maintaining 20 observed neighbours, a ratio consistent with a business network requiring transit connectivity rather than an access or hosting provider
- Traffic from this AS represents internal corporate operations, including web services, API endpoints, and office backhaul for a media company with over 130 titles and significant digital reader engagement
Notable
- The RDAP registrant
VLTAVA LABE MEDIA a.s.matches the AS holder, confirming direct ownership of the address space - Vltava Labe Media was acquired by Penta Investments in November 2015, transitioning from German ownership under Verlagsgruppe Passau to Czech private equity control
- The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, reflecting a consolidated corporate estate rather than a fragmented or multi-tenant allocation

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
