Formally, any DNS Resource Record (RR) may occur under any domain
name.  However, some services use an operational convention for
defining specific interpretations of an RRset by locating the records
in a DNS branch under the parent domain to which the RRset actually
applies.  The top of this subordinate branch is defined by a naming
convention that uses a reserved node name, which begins with the
underscore character (e.g., "_name").  The underscored naming
construct defines a semantic scope for DNS record types that are
associated with the parent domain above the underscored branch.  This
specification explores the nature of this DNS usage and defines the
"Underscored and Globally Scoped DNS Node Names" registry with IANA.
The purpose of this registry is to avoid collisions resulting from
the use of the same underscored name for different services.

This document is a product of the Domain Name System Operations Working Group of the IETF.
