The IQUERY method of performing inverse DNS lookups, specified in
RFC 1035, has not been generally implemented and has usually been
operationally disabled where it has been implemented.  Both reflect
a general view in the community that the concept was unwise and
that the widely-used alternate approach of using pointer (PTR) queries
and reverse-mapping records is preferable.  Consequently, this
document deprecates the IQUERY operation, declaring it entirely
obsolete.  This document updates RFC 1035.

This document is a product of the DNS Extensions Working Group of the
IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
