>How does IPv6 addressing work? Short version: 2000::/3 The currently active global unicast pool RIRx::/12 IANA (by default) assigns /12s to RIRs RIRx:ISPx::/32 RIRs (by default) assign /32s to ISPs RIRx:ISPx:ORGx::/48 ISPs (by default) assign /48s to enterprises (/56s to homes) RIRx:ISPx:ORGx:VLAN::/64 Enterprises 'subnet' their allocation into /64s (debate over [/126 | /127] to P2P links)

Can I just subnet it Use the IETF/RFC web interface, clearly shows what RFCs where deprecated by, or deprecate/update, a given doc: e.g. - http://tools.ietf.org/html/rfc2461 ... has an obsoleted by, updated by, and obsoletes ... >all like IPv4 but with room to grow or is each host really going to need its >own /84 or something?

Depends what you are looking for, and possibly your HW vendor of choice. <<SNIP>>
