I support this as it would be a nice feature for NP to have. There are still some free nntp that are reachable through IPV6 only and one has to use a tunnel prog for them. In addition to that it will be nescessary some day anyway...
in the end it shouldn't be a problem since the nntp protocol needs only elementary socket functions, it is rather isolated topic in the sense that it can be studied/added at any time without rewriting the program from scratch.
i found a reference to a IPv6 tunnel program here:
you just use the windows "hosts" file (look for "windows hosts file" on the internet, it is trivial), put there several names of the local host - you can use intelligible names like ip6.chello.nl and map to different ports.
127.0.0.1 ip6.chello.nl
127.0.0.1 ip6.home.nl
in time it won't be a problem to add it to newspro natively, for now you can use the workaround.
not really related to newspro, but one of the other things the IPv6 protocol offers over IPv4, if i read correctly, is the ability to multicast packets.
It would be very useful for cutting down the bandwidth required to stream audio/video feeds to multiple clients.
