The domains are not regular expressions, precisely because they are not 
suitable for use in the case. Some time down the line, you will wonder 
why you can't get web pages about the Airbus because *ads* matches 
eads.com and stops you from accessing the airbus domain.

What you can do is

address/adserver.com/172.0.0.1

which matches any thing in the adserver.com domain, ie *.adserver.com

It's also possible to dowload collections of adserver names and use them 
as a hosts file, to block specific domains.
