primary/secondary DNS server address

primary/secondary DNS server address

This configuration option allows a server to accept a text-based address and perform a database lookup to convert that address to an IP address that can be used by the network. If a message uses a host name address, it must be converted somehow to an IP address before it can be sent to the destination controller. When the controller has a DNS server address configured, then the DNS server is used to take the host name address and convert it to the IP address of the destination module and the message can be sent. The two fields are set to 0.0.0.0 by default.

Each octet of the IP address must be in the range of 0…255. The first octet cannot be 127 or greater than 223.
