I think we had to let ARIN know the time frame of deploying IPv6 and how many customers we expected to put on in the first couple years. They did not ask for an addressing scheme.
Reading over the RFC's and other IPv6 resources, we have decided to hand out /56's to small/home/SOHO customers and /48's to larger customers.
I'm just not able to wrap my brain around the subnetting that needs to be done on the router. Like i said before, i think i'm just over complicating it in my mind.
Will keep it simple, this is what I (and I suspect many others) do
/128 - Loopback (what else?) /126 - Router p2p /112 - Router LAN shared segments (p2mp) /64 - Single customer LAN segments (customers asking for basic IPv6) /56 - Customer wants multiple LANs, doesn't want to fill out justification form /48 - Customer wants multiple LANs, thinks /56 is too small (for some reason), needs for routing, wants rDNS delegation etc.etc.etc..
I'll point out that you can do rDNS delegation down to the /64 (or even the /124) level. As to documenting, I think that the ARIN IPv6 wiki (http:// getipv6.info) might be an excellent place to add such data. Owen
