TCPAddr2Name is a domain name service command to resolve the hostname for a given IP address.
Address is an Omnis Character field containing the IP address to convert to a hostname. The IP address is of the form 255.255.255.254
Hostname is an Omnis Character field which receives a hostname which maps to the IP address. The hostname is of the form machine[.domainame.dom]
Note: This command fails if the address of a Domain Name Server has not been defined for your computer. Not all host IP Addresses may be known to the Domain Name Server. If the Domain Name Server is busy or unavailable, the command times out and returns an error. Defining often -used servers in a local host’s file or using a caching Domain Name Server increases performance of this command.
