ICANN makes no comment on its proposed solutions, but feels the report adds to an understanding of the challenges in making changes to the current root zone glue management process. For that reason, ICANN wishes to share this Report with the DNS stakeholders.<o:p></o:p></span></p><p><span style='font-family:"Arial","sans-serif"'>Background:<o:p></o:p></span></p><p><span style='font-family:"Arial","sans-serif"'>ICANN initially consulted with the DNS community regarding how root zone glue records are managed in 2005 (<a href="http://forum.icann.org/lists/root-glue-comments/">http://forum.icann.org/lists/root-glue-comments/</a>). Glue records are used to identify the IP address of a name server, and are required under current root zone management processes. When multiple TLDs share the same name server, changes or updates to the name server's IP address will jointly affect each top-level domain. The requirement for all affected top-level domain operators to agree to such changes can lead to very lengthy processing times for these requests, even when there is urgency involved.<o:p></o:p></span></p><p><span style='font-family:"Arial","sans-serif"'>Since those initial discussions, and in the years following, IANA department staff have periodically encountered requests that affect a significant number of TLDs that share "glue". In 2009, ICANN commissioned Araneus Information Systems Oy (<a href="http://www.araneus.fi/">http://www.araneus.fi/</a>) to prepare an analysis of root zone glue management through the IANA root zone change process. Andreas Gustafsson of Araneus submitted the final version of his "<a href="http://www.icann.org/en/tlds/report-root-zone-glue-handling-nov09-en.pdf">Report on Root Zone Glue Handling</a>" in November 2009, and the IANA department has used this information for additional analysis of the impact of glue record changes in the root zone. No changes to the process are currently being proposed.<o:p></o:p></span></p></div></div><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0 width="100%" style='width:100.0%'><tr><td width="100%" style='width:100.0%;background:white;padding:0in 0in 0in 0in'><p style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:3.75pt;margin-left:0in;line-height:15.0pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#5E5E5E'>This message was sent to <a href="mailto:inne@icann.org">inne@icann.org</a> from:<o:p></o:p></span></p><p style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:3.75pt;margin-left:0in;line-height:15.0pt'><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#5E5E5E'>ICANN | 4676 Admiralty Way Suite 330 | Marina del Rey, CA 90292-6601<o:p></o:p></span></p></td><td width="2%" style='width:2.0%;background:white;padding:0in 0in 0in 0in'><p style='line-height:9.75pt'><span style='font-size:7.0pt;font-family:"Arial","sans-serif";color:#5E5E5E'>Email Marketing by <a href="http://www.icontact.com/a.pl/144186" target="_blank"><span style='text-decoration:none'><img border=0 id="_x0000_i1027" src="http://app.icontact.com/images/icontact_tryFree.gif" alt="iContact - Try It Free!"></span></a><o:p></o:p></span></p></td></tr></table><p class=MsoNormal><span style='font-family:"Arial","sans-serif";display:none'><o:p> </o:p></span></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0><tr><td style='background:white;padding:0in 0in 0in 0in'><p class=MsoNormal><a href="http://app.icontact.com/icp/mmail-mprofile.pl?r=9826907&l=6333&s=VMK0&m=353321&c=165637"><b><span style='font-size:9.0pt;font-family:"Arial","sans-serif";color:#115880;text-decoration:none'>Manage Your Subscription </span></b></a><o:p></o:p></p></td></tr></table><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'><img border=0 width=1 height=1 id="_x0000_i1028" src="http://click.icptrack.com/icp/track.php?msgid=353321&act=VMK0&r=9826907&c=165637"><o:p></o:p></span></p></div></body></html>
