Unclassified RIPE
Summary
PilsFree
isp infrastructure business
A registered association running a city's network, with an IPv6 allocation far larger than its IPv4 one.
What it's used for
- A Czech community internet network operated as a members' association. 1,024 addresses in one IPv4 prefix, one IPv6 prefix, and two observed BGP neighbours.
Notable
- The IPv4 inventory is
185.118.80.0/22, netnameCZ-PILSFREE-20150921. - The IPv6 prefix is
2a06:9280::/29. - The registered holder's name ends in
z. s., the Czech legal form for a voluntary association. - Three addresses were sampled and none returned a name.
Interesting
- Community networks are built by residents who wire up their own neighbourhoods and register an association to hold the address space, and they exist in the routing table on exactly the same terms as commercial operators. Nothing in BGP distinguishes a volunteer-run city network from a telecom, which is one of the genuinely democratic properties of the system.
- The IPv6 prefix is a /29, the largest an operator ordinarily receives, against 1,024 IPv4 addresses. The ratio is not an anomaly: IPv6 is allocated by policy rather than by demonstrated need, so an association with a thousand IPv4 addresses gets the same block a national carrier would ask for.
- The 2015 date and the
185.range put this registration after IPv4 exhaustion, when 1,024 addresses was close to the maximum a new entrant could obtain. A network serving a whole city on that much space is running carrier NAT or has moved a great deal of traffic to IPv6. - Two neighbours, which for a community network usually means one commercial transit and one exchange.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 1 downstream and 4 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, 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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
