GoKawiilHobbyist shows how to claim a free .arpa subdomain via Hurricane Electric's tunnelbroker
A blogger detailed a workaround for obtaining a personal domain under .arpa, the top-level domain normally reserved for internet infrastructure and closed to public registration. By signing up for a free IPv6 tunnel through Hurricane Electric's tunnelbroker.net service, users can claim reverse-DNS records under ip6.arpa and repurpose them to host arbitrary DNS entries, effectively creating a working website address ending in .arpa.
