The Domain Name System's wire protocol includes a number of fixed
fields whose range has been or soon will be exhausted and does not
allow requestors to advertise their capabilities to responders. This
document describes backward compatible mechanisms for allowing the
protocol to grow.
This document updates the EDNS0 specification (RFC 2671) based on
feedback from deployment experience in several implementations. It
also closes the IANA registry for extended labels created as part of
RFC 2671 and obsoletes RFC 2673 ("Binary Labels in the Domain Name
System") which depends on the existence of extended labels.
