+## Example of valid patterns:

+## ads.*         | matches anything with an "ads." prefix
+## *.example.com | matches example.com and all names within that zone such as www.example.com
+## example.com   | identical to the above
+## =example.com  | block example.com but not *.example.com
+## *sex*         | matches any name containing that substring
+## ads[0-9]*     | matches "ads" followed by one or more digits
+## ads*.example* | *, ? and [] can be used anywhere, but prefixes/suffixes are faster
