This
document defines changes to the Domain Name System to support renumberable and
aggregatable IPv6 addressing. The changes include a new resource record type to
store an IPv6 address in a manner that expedites network renumbering and
updated definitions of existing query types that return Internet addresses as
part of additional section processing.
For
lookups keyed on IPv6 addresses (often called reverse lookups), this document
defines a new zone structure that allows a zone to be used without modification
for parallel copies of an address space (as for a multihomed provider or site)
and across network renumbering events.
