[HECnet] PyDECnet and IPv6

Why? Because I felt like it and it wasn't too hard. I have a PyDECnet version that can handle not just IPv4 but also IPv6. It's on node PYTHON right now and on the map server 28NH (at akdesign.dyndns.org). This applies both to the web interface and also to the various IP-based datalink protocols. I've tested Multinet, GRE, Ethernet (UDP bridge) and DDCMP. If anyone is interested in using this with PYTHON, let me know. Unfortunately dyndns.org doesn't support IPv6 records well; I can enter one manually but it disappears after a while for reasons I do not understand. It's there now. You can access the mapper's web page (akdesign.dyndns.org:8080) that way if you like. paul
