The tertiary DNS server is optional and used only if the primary and secondary nameservers fail.
Nameservers specified here MUST be registered nameservers (e.g. ns1.mycompany.com and ns2.mycompany.com) NOT just an IP Address.
You DO NOT need to specify the IP address of the nameserver here. InterWorx does not need that information.
