Dnsmasq address= directive failing for some long subdomains

[paftdunk]

I make extensive use of the address= directive to globally block known tracking domains. I've noticed that some long domains, particularly those with multiple periods tend to get past this matching mechanism.

One of my entries is address=/.online-metrix.net/

I just had this subdomain roll past and successfully resolve:

Any suggestions on a workaround to this general class of problem?
