This feature may or may not already be supported by the library imported here:
https://github.com/koinos/koinos-jsonrpc/blob/master/cmd/koinos-jsonrpc/main.go#L22

The first step would be to pass in a valid IPv6 address as a listen parameter to see if it works. We pass the argument in to the library here:
https://github.com/koinos/koinos-jsonrpc/blob/master/cmd/koinos-jsonrpc/main.go#L136

If it doesn't "just work," then we should investigate the requirements of the library and go from there.

Makes total sense. Will do the same and see if it works then proceed from there.
