>How does IPv6 addressing work?
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)

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 ...

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