&nbsp;&nbsp;&nbsp;who&nbsp;must&nbsp;keep&nbsp;track&nbsp;of&nbsp;the&nbsp;names,&nbsp;addresses,&nbsp;contacts,&nbsp;and&nbsp;other&nbsp;data&nbsp;<BR>
&nbsp;&nbsp;&nbsp;in&nbsp;a&nbsp;database.&nbsp;&nbsp;The&nbsp;longer&nbsp;the&nbsp;name,&nbsp;the&nbsp;more&nbsp;likely&nbsp;the&nbsp;data&nbsp;<BR>

&nbsp;&nbsp;&nbsp;names.&nbsp;&nbsp;Most&nbsp;people&nbsp;agree&nbsp;that&nbsp;short&nbsp;names&nbsp;are&nbsp;easier&nbsp;to&nbsp;remember&nbsp;and&nbsp;<BR>
&nbsp;&nbsp;&nbsp;type;&nbsp;most&nbsp;domain&nbsp;names&nbsp;registered&nbsp;so&nbsp;far&nbsp;are&nbsp;12&nbsp;characters&nbsp;or&nbsp;fewer.&nbsp;<BR>

&nbsp;&nbsp;&nbsp;Domain&nbsp;name&nbsp;assignments&nbsp;are&nbsp;made&nbsp;on&nbsp;a&nbsp;first-come-first-served&nbsp;basis.&nbsp;<BR>
&nbsp;&nbsp;&nbsp;The&nbsp;NIC&nbsp;has&nbsp;chosen&nbsp;not&nbsp;to&nbsp;register&nbsp;individual&nbsp;hosts&nbsp;directly&nbsp;under&nbsp;<BR>
&nbsp;&nbsp;&nbsp;the&nbsp;top-level&nbsp;domains&nbsp;it&nbsp;administers.&nbsp;&nbsp;One&nbsp;advantage&nbsp;of&nbsp;the&nbsp;domain&nbsp;<BR>
&nbsp;&nbsp;&nbsp;naming&nbsp;system&nbsp;is&nbsp;that&nbsp;administration&nbsp;and&nbsp;data&nbsp;maintenance&nbsp;can&nbsp;be&nbsp;<BR>
&nbsp;&nbsp;&nbsp;delegated&nbsp;down&nbsp;a&nbsp;hierarchical&nbsp;tree.&nbsp;&nbsp;Registration&nbsp;of&nbsp;hosts&nbsp;at&nbsp;the&nbsp;<BR>
&nbsp;&nbsp;&nbsp;same&nbsp;level&nbsp;in&nbsp;the&nbsp;tree&nbsp;as&nbsp;a&nbsp;second-level&nbsp;domain&nbsp;would&nbsp;dilute&nbsp;the&nbsp;<BR>
&nbsp;&nbsp;&nbsp;usefulness&nbsp;of&nbsp;this&nbsp;feature.&nbsp;&nbsp;In&nbsp;addition,&nbsp;the&nbsp;administrator&nbsp;of&nbsp;a&nbsp;<BR>
&nbsp;&nbsp;&nbsp;domain&nbsp;is&nbsp;responsible&nbsp;for&nbsp;the&nbsp;actions&nbsp;of&nbsp;hosts&nbsp;within&nbsp;his&nbsp;domain.&nbsp;&nbsp;We&nbsp;<BR>
&nbsp;&nbsp;&nbsp;would&nbsp;not&nbsp;want&nbsp;to&nbsp;find&nbsp;ourselves&nbsp;in&nbsp;the&nbsp;awkward&nbsp;position&nbsp;of&nbsp;policing&nbsp;<BR>
&nbsp;&nbsp;&nbsp;the&nbsp;actions&nbsp;of&nbsp;individual&nbsp;hosts.&nbsp;&nbsp;Rather,&nbsp;the&nbsp;subdomains&nbsp;registered&nbsp;<BR>
&nbsp;&nbsp;&nbsp;under&nbsp;these&nbsp;top-level&nbsp;domains&nbsp;retain&nbsp;the&nbsp;responsibility&nbsp;for&nbsp;this&nbsp;<BR>
&nbsp;&nbsp;&nbsp;function.&nbsp;<BR>
&nbsp;<BR>
&nbsp;&nbsp;&nbsp;Countries&nbsp;that&nbsp;wish&nbsp;to&nbsp;be&nbsp;registered&nbsp;as&nbsp;top-level&nbsp;domains&nbsp;are&nbsp;<BR>
&nbsp;&nbsp;&nbsp;required&nbsp;to&nbsp;name&nbsp;themselves&nbsp;after&nbsp;the&nbsp;two-letter&nbsp;country&nbsp;code&nbsp;listed&nbsp;<BR>
&nbsp;&nbsp;&nbsp;in&nbsp;the&nbsp;international&nbsp;standard&nbsp;ISO-3166.&nbsp;&nbsp;In&nbsp;some&nbsp;cases,&nbsp;however,&nbsp;the&nbsp;<BR>
&nbsp;&nbsp;&nbsp;two-letter&nbsp;ISO&nbsp;country&nbsp;code&nbsp;is&nbsp;identical&nbsp;to&nbsp;a&nbsp;state&nbsp;code&nbsp;used&nbsp;by&nbsp;the&nbsp;<BR>
&nbsp;&nbsp;&nbsp;U.S.&nbsp;Postal&nbsp;Service.&nbsp;&nbsp;Requests&nbsp;made&nbsp;by&nbsp;countries&nbsp;to&nbsp;use&nbsp;the&nbsp;three-&nbsp;<BR>
&nbsp;&nbsp;&nbsp;letter&nbsp;form&nbsp;of&nbsp;country&nbsp;code&nbsp;specified&nbsp;in&nbsp;the&nbsp;ISO-3166&nbsp;standard&nbsp;will&nbsp;<BR>
&nbsp;&nbsp;&nbsp;be&nbsp;considered&nbsp;in&nbsp;such&nbsp;cases&nbsp;so&nbsp;as&nbsp;to&nbsp;prevent&nbsp;possible&nbsp;conflicts&nbsp;and&nbsp;<BR>

&nbsp;&nbsp;&nbsp;The&nbsp;APPENDIX&nbsp;to&nbsp;this&nbsp;memo&nbsp;contains&nbsp;the&nbsp;application&nbsp;form&nbsp;for&nbsp;<BR>
&nbsp;&nbsp;&nbsp;registering&nbsp;a&nbsp;top-level&nbsp;or&nbsp;second-level&nbsp;domain&nbsp;with&nbsp;the&nbsp;NIC.&nbsp;&nbsp;It&nbsp;<BR>
&nbsp;&nbsp;&nbsp;supersedes&nbsp;the&nbsp;version&nbsp;of&nbsp;the&nbsp;questionnaire&nbsp;found&nbsp;in&nbsp;RFC-920.&nbsp;&nbsp;The&nbsp;<BR>
&nbsp;&nbsp;&nbsp;application&nbsp;should&nbsp;be&nbsp;submitted&nbsp;by&nbsp;the&nbsp;person&nbsp;administratively&nbsp;<BR>
&nbsp;&nbsp;&nbsp;responsible&nbsp;for&nbsp;the&nbsp;domain,&nbsp;and&nbsp;must&nbsp;be&nbsp;filled&nbsp;out&nbsp;completely&nbsp;before&nbsp;<BR>
&nbsp;&nbsp;&nbsp;the&nbsp;NIC&nbsp;will&nbsp;authorize&nbsp;establishment&nbsp;of&nbsp;a&nbsp;top-level&nbsp;or&nbsp;second-level&nbsp;<BR>
&nbsp;&nbsp;&nbsp;domain.&nbsp;&nbsp;The&nbsp;DA&nbsp;is&nbsp;responsible&nbsp;for&nbsp;keeping&nbsp;his&nbsp;domain's&nbsp;data&nbsp;current&nbsp;<BR>

&nbsp;&nbsp;&nbsp;outlines&nbsp;this&nbsp;procedure.&nbsp;&nbsp;It&nbsp;is&nbsp;highly&nbsp;recommended&nbsp;that&nbsp;the&nbsp;DA&nbsp;review&nbsp;<BR>
&nbsp;&nbsp;&nbsp;this&nbsp;information&nbsp;periodically&nbsp;and&nbsp;provide&nbsp;any&nbsp;corrections&nbsp;or&nbsp;<BR>

&nbsp;<BR>
&nbsp;&nbsp;&nbsp;The&nbsp;designers&nbsp;of&nbsp;the&nbsp;domain-naming&nbsp;system&nbsp;initiated&nbsp;several&nbsp;general&nbsp;<BR>
&nbsp;&nbsp;&nbsp;categories&nbsp;of&nbsp;names&nbsp;as&nbsp;top-level&nbsp;domain&nbsp;names,&nbsp;so&nbsp;that&nbsp;each&nbsp;could&nbsp;<BR>
&nbsp;&nbsp;&nbsp;accommodate&nbsp;a&nbsp;variety&nbsp;of&nbsp;organizations.&nbsp;&nbsp;The&nbsp;current&nbsp;top-level&nbsp;<BR>
&nbsp;&nbsp;&nbsp;domains&nbsp;registered&nbsp;with&nbsp;the&nbsp;DDN&nbsp;Network&nbsp;Information&nbsp;Center&nbsp;are&nbsp;ARPA,&nbsp;<BR>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;of&nbsp;the&nbsp;label&nbsp;&quot;.ARPA&quot;&nbsp;in&nbsp;order&nbsp;to&nbsp;accelerate&nbsp;a&nbsp;transition&nbsp;to&nbsp;the&nbsp;<BR>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;was&nbsp;to&nbsp;force&nbsp;hosts&nbsp;to&nbsp;become&nbsp;accustomed&nbsp;to&nbsp;using&nbsp;the&nbsp;new&nbsp;style&nbsp;<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;names&nbsp;and&nbsp;to&nbsp;modify&nbsp;their&nbsp;network&nbsp;software,&nbsp;if&nbsp;necessary.&nbsp;&nbsp;This&nbsp;<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;was&nbsp;done&nbsp;on&nbsp;a&nbsp;network-wide&nbsp;basis&nbsp;and&nbsp;was&nbsp;directed&nbsp;by&nbsp;DCA&nbsp;in&nbsp;DDN&nbsp;<BR>

&nbsp;<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&quot;NET&quot;&nbsp;was&nbsp;introduced&nbsp;as&nbsp;a&nbsp;parent&nbsp;domain&nbsp;for&nbsp;various&nbsp;network-type&nbsp;<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;organizations.&nbsp;&nbsp;Organizations&nbsp;that&nbsp;belong&nbsp;within&nbsp;this&nbsp;top-level&nbsp;<BR>

&nbsp;<BR>
&nbsp;&nbsp;&nbsp;One&nbsp;of&nbsp;the&nbsp;guidelines&nbsp;in&nbsp;effect&nbsp;in&nbsp;the&nbsp;domain-naming&nbsp;system&nbsp;is&nbsp;that&nbsp;a&nbsp;<BR>
&nbsp;&nbsp;&nbsp;host&nbsp;should&nbsp;have&nbsp;only&nbsp;one&nbsp;name&nbsp;regardless&nbsp;of&nbsp;what&nbsp;networks&nbsp;it&nbsp;is&nbsp;<BR>
&nbsp;&nbsp;&nbsp;connected&nbsp;to.&nbsp;&nbsp;This&nbsp;implies,&nbsp;that,&nbsp;in&nbsp;general,&nbsp;domain&nbsp;names&nbsp;should&nbsp;<BR>
&nbsp;&nbsp;&nbsp;not&nbsp;include&nbsp;routing&nbsp;information&nbsp;or&nbsp;addresses.&nbsp;&nbsp;For&nbsp;example,&nbsp;a&nbsp;host&nbsp;<BR>
&nbsp;&nbsp;&nbsp;that&nbsp;has&nbsp;one&nbsp;network&nbsp;connection&nbsp;to&nbsp;the&nbsp;Internet&nbsp;and&nbsp;another&nbsp;to&nbsp;BITNET&nbsp;<BR>
&nbsp;&nbsp;&nbsp;should&nbsp;use&nbsp;the&nbsp;same&nbsp;name&nbsp;when&nbsp;talking&nbsp;to&nbsp;either&nbsp;network.&nbsp;&nbsp;For&nbsp;a&nbsp;<BR>
&nbsp;&nbsp;&nbsp;description&nbsp;of&nbsp;the&nbsp;syntax&nbsp;of&nbsp;domain&nbsp;names,&nbsp;please&nbsp;refer&nbsp;to&nbsp;Section&nbsp;3&nbsp;<BR>
&nbsp;&nbsp;&nbsp;of&nbsp;RFC-1034.&nbsp;<BR>
&nbsp;<BR>
VERIFICATION&nbsp;OF&nbsp;DATA&nbsp;<BR>
&nbsp;<BR>
&nbsp;&nbsp;&nbsp;The&nbsp;verification&nbsp;process&nbsp;can&nbsp;be&nbsp;accomplished&nbsp;in&nbsp;several&nbsp;ways.&nbsp;&nbsp;One&nbsp;of&nbsp;<BR>
&nbsp;&nbsp;&nbsp;these&nbsp;is&nbsp;through&nbsp;the&nbsp;NIC&nbsp;WHOIS&nbsp;server.&nbsp;&nbsp;If&nbsp;he&nbsp;has&nbsp;access&nbsp;to&nbsp;WHOIS,&nbsp;<BR>
