Works for me; but then I use "outdated" software: OpenBSD 3.8.

Are you sure your browser is asking for exactly that name, and not
some name in those domains you specified?  For those cases I simply
add the domains with a wildcard to my local DNS server, e.g.,

named.conf:
zone "doubleclick.com" {
        type master;
        file "master/doubleclick.com";
};

master/doubleclick.com:
[[usual SOA]]
ad.doubleclick.com.     IN      A       127.0.0.1
*.doubleclick.com.      IN      A       127.0.0.1
