About this network

AS4830ORG is held by 4830.org e. V., a German non-profit association operating Freifunk community networks.

What it's used for

• The address space carries community wireless infrastructure, evidenced by netnames DE-MAILDE-20191030 and DE-4830org-HAM-20210525, and reverse DNS entries like bcast-ffgt.uu.org and gw-fallback.uu.org which reference Freifunk Gütersloh (ffgt) and general Freifunk gateway/broadcast functions.
• The AS announces 1024 IPv4 addresses across 3 prefixes and 14 IPv6 prefixes, while maintaining 112 observed neighbours. This high neighbour-to-address ratio indicates a transit or peering-heavy role typical of a community network exchanging routes with multiple upstreams and peers rather than serving a large dense subscriber base.
• Traffic consists of community Wi-Fi access points and gateway nodes for Freifunk users in regions like Gütersloh and Müritz, providing free, open internet access to the public.

Notable

• Registrants for the primary prefixes align with the announcer, listing 4830.org e. V. Technik and mail.de GmbH for the largest block, while the smallest prefix 192.251.226.0/24 is registered to unknown under netname HISPNET.
• The address inventory is small and fragmented, with a mix of legacy and newer allocations, consistent with a volunteer-run organization managing infrastructure across multiple geographic sites.
