DNS and domain functions

DNS and domain functions enable you to perform domain name lookups and validate fully qualified domain names.

You can use the DNS and domain functions to perform name lookups of the TADDM server and names extracted from a remote configuration. You can also use the functions to validate a fully qualified domain name (FQDN).

Table 1 describes functions you can use.
