If we don鈥檛 have a registry-specific form, the General Protocol Registration Request Form should be used.</p> <p>Before you submit a request, check the registry for its registration procedure(s) and reference document(s). Common procedures are defined in <a href="/go/rfc8126">RFC 8126</a>, but the RFC that defines the registry may include more detailed instructions. You can find a list of registries <a href="/protocols">here</a>.</p> <p>Note: if a registration procedure requires RFC publication, it may be possible to obtain an early allocation. Early allocations are marked as TEMPORARY in the registry and must be reviewed annually. Early allocation requests must be submitted by the relevant IETF WG chair. For further requirements, see <a href="/go/rfc7120">RFC 7120</a>.</p> <table class="iana-table"> <thead> <tr> <th>Registry</th> <th>Registration Form</th> </tr> </thead> <tbody> <tr> <td>Private Enterprise Numbers (PEN)</td> <td><a href="https://pen.iana.org/pen/PenApplication.page">Request PEN Assignment</a><br/> <a href="https://pen.iana.org/pen/ModifyPen.page">Modify Existing PEN Assignment</a></td> </tr> <tr> <td>Multicast Addresses</td> <td><a href="/form/multicast-ipv4">Request IPv4 Assignment</a><br/> <a href="/form/multicast-ipv6">Request IPv6 Assignment</a> </td> </tr> <tr> <td>Media Types</td> <td><a href="/form/media-types">Request Media Type Registration</a></td> </tr> <tr> <td>Port Numbers and Service Names</td> <td><a href="/form/ports-services">Request Port Number and/or Service Name Assignment</a><br/> <a href="/form/port-modification">Modify Existing Port Number/Service Name Assignment</a> </td> </tr> <tr><td>ifTypes</td> <td><a href="/form/iftype">Request ifType Assignment</a></td> </tr> <tr> <td>tunnelTypes</td> <td><a href="/form/tunneltype">Request tunnelType Assignment</a></td> </tr> <tr> <td>Media Feature Tags</td> <td>Use <a href="/protocols/media-feature-tag-template.txt">Media Feature Tag Template</a> and submit to <span class="email">iana@iana.org</span></td> </tr> <tr> <td>All other protocol registries</td> <td><a href="/form/protocol-assignment">General Protocol Registration Request Form</a></td> </tr> </tbody> </table> </main> <nav id="sidenav"> <div class="navigation_box"> <h2>Protocol Registries</h2> <ul> <li id="nav_prot_reg"><a href="/protocols">Protocol Registries</a></li> <li id="nav_prot_tz"><a href="/time-zones">Time Zone Database</a></li> <li id="nav_prot_performance"><a href="/performance/ietf-statistics">Performance</a></li> <li id="nav_prot_status"><a href="/performance/ietf-draft-status">IETF Draft Status</a></li> </ul> </div> </nav> </article> </div> <footer> <div id="footer"> <table class="navigation"> <tr> <td class="section"><a href="/domains">Domain Names</a></td> <td class="subsection"> <ul> <li><a href="/domains/root">Root Zone Registry</a></li> <li><a href="/domains/int">.INT Registry</a></li> <li><a href="/domains/arpa">.ARPA Registry</a></li> <li><a href="/domains/idn-tables">IDN Repository</a></li> </ul> </td> </tr> <tr> <td class="section"><a href="/numbers">Number Resources</a></td> <td class="subsection"> <ul> <li><a href="/abuse">Abuse Information</a></li> </ul> </td> </tr> <tr> <td class="section"><a href="/protocols">Protocols</a></td> <td class="subsection"> <ul> <li><a href="/protocols">Protocol Registries</a></li> <li><a href="/time-zones">Time Zone Database</a></li> </ul> </td> </tr> <tr> <td class="section"><a href="/about">About Us</a></td> <td class="subsection"> <ul> <li><a href="/news">News</a></li> <li><a href="/performance">Performance</a></li> <li><a href="/about/excellence">Excellence</a></li> <li><a href="/archive">Archive</a></li> <li><a href="/contact">Contact Us</a></li> </ul> </td> </tr> </table> <div id="custodian"> <p>The IANA functions coordinate the Internet鈥檚 globally unique identifiers, and are provided by <a href="http://pti.icann.org">Public Technical Identifiers</a>, an affiliate of <a href="http://www.icann.org/">ICANN</a>.</p> </div> <div id="legalnotice"> <ul> <li><a href="https://www.icann.org/privacy/policy">Privacy Policy</a></li> <li><a href="https://www.icann.org/privacy/tos">Terms of Service</a></li> </ul> </div> </div> </footer> <script> $(document).ready(function() { $("#nav_prot_reg").addClass("selected") }); </script> </body> </html>
