We pick b.root-servers.net, one of the 13 root servers (1), and ask it about ns2.thaismartdns.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that thaismartdns.com is delegated to two name servers, including ns2.thaismartdns.com (3), so we ask that one and get the following answer:
All of them use only the IPv4 number 202.142.212.8 (example: r-u-indy.com ). Worth noting is that seven of the domains that only use the IPv4 number 202.142.212.8 use name server group 1.
All of them use the primary name server ns1.thaismartdns.com. Worth noting is that eleven of the domains that use the primary name server ns1.thaismartdns.com use name server group 1.
The primary name server ns1.thaismartdns.com only
Eleven of the twelve domains that use the primary name server ns1.thaismartdns.com use name server group 1. Worth noting is that all of the domains that use name server group 1 use the primary name server ns1.thaismartdns.com.
The IPv4 number 202.142.212.8 only
There are more than hundred domains that only use the IPv4 number 202.142.212.8.
The three name servers borsubs, ns1.thai-dns.net and ns2.thai-dns.net together
There are about twenty domains that use the three name servers borsubs, ns1.thai-dns.net and ns2.thai-dns.net together, hereafter referred to as "name server group 2".
There are ten domains that use the primary name server borsubs.
Seven of those use the name server borsubs only (but neither ns1 nor ns2.thai-dns.net ). Worth noting is that seven of the domains that use the name server borsubs only (but neither ns1 nor ns2.thai-dns.net ) use the primary name server borsubs.
Three of them use the three name servers , and ns2 together, hereafter referred to as "name server group 3", (example: siamball.com ). Worth noting is that three of the domains that use name server group 3 use the primary name server borsubs.
