AS49009 FFHH
Unclassified RIPE
Summary
Freifunk Hamburg
freifunk community non-profit germany
The AS handle FFHH is held by Freifunk Hamburg (Freifunk Rheinland e.V.).
What it's used for
- The space carries community wireless access, evidenced by the reverse DNS record
nat-64-gw02-new.hamburg.freifunk.netpointing to a NAT64 gateway. - The AS announces 256 IPv4 addresses and 1 IPv6 prefix, maintaining 89 observed neighbours; this high neighbour-to-address ratio indicates a transit or peering-heavy role typical of community networks exchanging routes with multiple providers.
- Traffic from this AS consists of community members accessing the internet via the Freifunk mesh network, with the NAT64 infrastructure facilitating IPv6 connectivity for the local user base.
Notable
- The RDAP registrant for the announced IPv4 block is
IPHH Internet Port Hamburg GmbH, which differs from the AS holder, indicating the address space is leased or allocated by a third-party provider. - The address inventory is minimal, consisting of a single /24 IPv4 block and a /32 IPv6 prefix, consistent with a small-scale community operation rather than a large commercial ISP.

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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
