You are also likely to screw up and end up banning legitimate users
who happen to use DynDns for perfectly valid reasons.
I would suggest that you abandon trying to ban users based on domain,
or IP, and focus on their actual content/contributions
post-registration.
As a bonus, by banning users based on content and not email address,
you'll also catch those who use "valid" email addresses that you'd
never be able to "rule out" in any predictive sensible way.
