In short? 99.8% of the time, they are these:<\/p>\n

ns1.coza.net.za.   IN A 66.135.62.20\r\nns.coza.net.za.    IN A 206.223.136.200\r\nns4.iafrica.com.   IN A 196.7.142.131\r\nns0.is.co.za.      IN A 196.4.160.17\r\nns0.neotel.co.za.  IN A 41.160.0.4\r\ncoza1.dnsnode.net. IN A 194.146.106.74<\/pre>\n
And the remaining 0.2% of the time?\u00a0 Let’s ask the root servers – what are the NS records for co.za:<\/p>\n
# dig @a.root-servers.net ns co.za<\/strong>\r\n ;; AUTHORITY SECTION:\r\n za. 172800 IN NS za1.dnsnode.net.\r\n za. 172800 IN NS nsza.is.co.za.\r\n za. 172800 IN NS za-ns.anycast.pch.net.\r\n za. 172800 IN NS sns-pb.isc.org.\r\n za. 172800 IN NS disa.tenet.ac.za.\r\n ;; ADDITIONAL SECTION:\r\n za1.dnsnode.net. 172800 IN A 194.146.106.78<\/strong>\r\n nsza.is.co.za. 172800 IN A 196.4.160.27\r\n za-ns.anycast.pch.net. 172800 IN A 204.61.216.55\r\n sns-pb.isc.org. 172800 IN A 192.5.4.1\r\n disa.tenet.ac.za. 172800 IN A 196.21.79.50<\/pre>\n
Okay, that gets us za. Let’s ask one of them:<\/p>\n
# dig @194.146.106.78 ns co.za<\/strong>\r\n ;; ANSWER SECTION:\r\n co.za. 3600 IN NS ns0.is.co.za.\r\n co.za. 3600 IN NS ns1.coza.net.za.\r\n co.za. 3600 IN NS ns4.iafrica.com.\r\n co.za. 3600 IN NS ns0.neotel.co.za.\r\n co.za. 3600 IN NS ns.coza.net.za.<\/strong>\r\n co.za. 3600 IN NS coza1.dnsnode.net.<\/pre>\n
Cool – we have names, but we don’t have IP addresses yet.\u00a0 So let’s go and find out what the IP address of ns.coza.net.za<\/strong> is.\u00a0 We already know the NS servers for .za<\/strong> but let’s pretend we don’t:<\/p>\n
dig @a.root-servers.net ns.coza.net.za a<\/strong>\r\n za. 172800 IN NS za1.dnsnode.net.\r\n za. 172800 IN NS disa.tenet.ac.za.\r\n za. 172800 IN NS nsza.is.co.za.\r\n za. 172800 IN NS za-ns.anycast.pch.net.\r\n za. 172800 IN NS sns-pb.isc.org.\r\n\r\n;; ADDITIONAL SECTION:\r\n za1.dnsnode.net. 172800 IN A 194.146.106.78\r\n disa.tenet.ac.za. 172800 IN A 196.21.79.50\r\n nsza.is.co.za. 172800 IN A 196.4.160.27<\/strong>\r\n za-ns.anycast.pch.net. 172800 IN A 204.61.216.55\r\n sns-pb.isc.org. 172800 IN A 192.5.4.1<\/pre>\n
They say to ask the .net.za servers, and provide glue. Cool:<\/p>\n
# dig @196.4.160.27 a ns.coza.net.za<\/strong>\r\n ;; AUTHORITY SECTION:\r\n net.za. 86400 IN NS disa.tenet.ac.za.\r\n net.za. 86400 IN NS ns0.is.co.za.\r\n net.za. 86400 IN NS za-ns.anycast.pch.net.\r\n\r\n;; ADDITIONAL SECTION:\r\n ns0.is.co.za. 86400 IN A 196.4.160.17\r\n disa.tenet.ac.za. 86400 IN A 196.21.79.50<\/pre>\n
Let’s choose one of those that we happen to have glue for (we don’t want to be here all day):<\/p>\n
# dig @196.4.160.17 ns.coza.net.za<\/strong>\r\n ;; AUTHORITY SECTION:\r\n coza.net.za. 86400 IN NS beth.coza.net.za.\r\n coza.net.za. 86400 IN NS secdns1.posix.co.za.<\/strong>\r\n coza.net.za. 86400 IN NS ns1.coza.net.za.\r\n\r\n;; ADDITIONAL SECTION:\r\n ns1.coza.net.za. 86400 IN A 66.135.62.20\r\n beth.coza.net.za. 86400 IN A 206.223.136.193\r\n beth.coza.net.za. 86400 IN AAAA 2001:43f8:30::193<\/pre>\n
Let’s ask “secdns1.posix.co.za<\/strong>” – oh wait, we don’t have the NS for co.za<\/strong> yet and this is what we are trying to find out, so we’re sunk.\u00a0 This is a DNS loop.<\/p>\n
What is the probability of this error? Well, for a single query, the probability is 0.2 % – 1 in 500 or so. A simple way to understand this is that 500 international users connect to your .co.za web site, then 499 will find it, and 1 will not.<\/p>\n
