DNS Translation File

A DNS Translation File consists of a list of DNS name pairs, consisting of a match and a replacement. When the file is used, the match is converted to the replacement, which is then passed to the resolver.

Special characters can be used in the match:

Character Usage
?  Wildcard for a single character.
*  Wildcard for multiple characters.
 #  Comment.

Note: Wildcards can only be used in the match, not the replacement.
