Abstract:
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 EDNS(0) specification (and obsoletes 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.
