Unclassified RIPE
Summary
Freenet Liberec
non-profit regional czechia community
The AS handle LBCFREE is operated by Freenet Liberec, z.s.
What it's used for
- The address space carries community network infrastructure, evidenced by the reverse DNS record
gw-f.lbcfree.netand the netnameCZ-LBCFREE-20170307. - The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, while maintaining 302 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large-scale access network.
Notable
- The RDAP registrants for the announced prefix
185.193.84.0/22align with the announcer, listing Freenet Liberec, z.s. and its administrative contacts. - Secondary sources identify the operator as a non-profit organization with a regional scope, consistent with its community network identity.
- The inventory consists of a single IPv4 prefix and one IPv6 prefix, representing a compact address estate.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
