Use Wildcard
If this option is enabled, subdomains of the registered domain will also be resolved to the same IP address.
For example, if test.dyndns.org has been registered and the IP address it is resolved to is a.b.c.d., all
subdomains like dns.test.dyndns.org will also get resolved to a.b.c.d. However, this will work only if the
dynamic DNS server supports this option.
Custom DNS
If enabled, this option specifies the domain name registered is of custom type. Also, its specified server
belongs to custom type.
Check IP
If enabled, this option specifies the RouteFinder will use the Check IP utility to verify the IP addresses that
are already registered for the domain name configured.
Check IP Server
Enter the name of the IP Address of the Check IP server.
Check IP Port
