Hi all, Sorry for the slight off-topic. I'm testing in my systems the idea of using IPv6 for Amateur Radio. My idea is to use some way of encoding the callsign in the IPv6 address. I'm using this proposal in my systems: https://github.com/darconeous/ham-addr/blob/master/ham-addr.txt.md Certainly, there are several other proposals that could be used. The good thing about IPv6 is that due to the large address space it's possible to make it mandatory to encode the callsign in the last 64 bits of the address. This eliminates the problem that we have in IPv4 of trying to trace back which callsign is behind an IP. The idea is to make some sort of whitelist of globally routable subnets that are using some way of encoding the callsign into the IPv6 (I would like to allow for the admin of a net to choose the encoding he wants to use). This whitelist can then be used in a firewall for several things: allowing access to some services to Amateurs only or deciding if a packet is fit to be routed by an RF link (for instance, one could require that the source and destination have both their callsigns encoded in their IPv6's). I'm using the subnet 2001:470:6915:8000::/49 for these tests. If someone has IPv6 connectivity and wants to try, there's a mumble server and a DX cluster (telnet port 7300) at ea4gpz.destevez.net (its IPv6 has the callsign EA4GPZ-Z encoded). The long term goal would be to have something similar to the 44net but where each user is using subnets allocated directly from their ISP instead of having a large block for amateurs (like the 44.0.0.0/8). Connectivity between different amateur subnets would run over the IPv6 internet instead of using a mesh VPN (as the IPIP mesh of 44net). The whitelist could be used to decide which IPv6's are amateur and get "special treatment". I have a longer text describing these ideas, but it's in Spanish. I'll translate it and put it somewhere, but I want to keep this email short enough. So, is anyone doing something similar already? I would like to get some subnets into the whitelist, so I can test how well this works. Questions, suggestions, comments? Anyone interested in joining these tests? 73, Dani EA4GPZ.
