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 obsoletes RFC 2673 ("Binary Labels in the
Domain Name System") and adds considerations on the use of extended
labels in the DNS.
