IPv6 & Ham Radio

Back in 1998, Naoto Shimazaki, 7L4FEP described an idea for use of IPv6 over the amateur radio in a document he presented to a TAPR Digital Communication Conference.

"IPv6 has huge address space and it supports real-time traffic. IPv6 realize new applications. For example, managing IPv4 address is not easy. It is possible to encode our "call sign" into IPv6 address. It enables us to managing IP address much easier."

You can read the whole thing here.

A few members from the Mesa Amateur Radio Club of Arizona took this to code.

"Club Members Jacques N1ZZH and Vinnie N1LQJ have developed a method of embedding a 2x5 (7 Character) callsign plus up to 185 nodes, plus 1 universal bit and three reserved bits in the 2nd octet, and a 16 bit amateur radio identifer at bit 24 of an IPv6 /64 Subnet address."

They announced;

"Tools for encoding and decoding amateur radio callsigns, up to 2x4 & 185 nodes, from IPv6 /64 subnets with Universal bit support and Amateur Radio Flag at the 24bit. Experimental RFC to IETF is being submitted for this proposed amateur standard."
