Usage
Use this command to define rule expressions to match full or partial host names (domain names).
The rule will be matched for the learnt IP addresses resolved from DNS queries to the specified domain
names. DNS responses for the specified domain names will be snooped and the learnt IP addresses stored.
Besides being used for standard rule matching, this command also enables the DNS Snooping feature if the
rulebase references any ruledefs with this configuration. The DNS protocol analyzer must also be enabled in
the rulebase.
