<b>Private-Use TLDs</b>. In networking terms, they are similar to Private IP Addresses where such addresses are not routable over the Internet, and are only used for Intranet and privately-used networks.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-left:36.0pt;text-align:justify"><i><span lang="EN-US" style="color:#0070C0">The need for private-use identifiers is not unique for domain names, and a useful analogy can be drawn between the uses of private IP address space
and those of a private-use TLD. Network operators use private IP address space to number resources not intended to be externally accessible, and private-use TLDs are used by network operators in a similar fashion. This document proposes reserving a string
in a manner similar to the current use of private IP address space. A similar rationale can be used to reserve more strings in case the need arises.<o:p></o:p></span></i></p>
