Unfortunately squidGuard doesn't do this AFAIK. We always enter sites by
both url and ip when we put stuff in local-block. Since the rest of the
domains don't have both url and ip, at least for everything, it sadly is
open to that extent. It would be great if this could be added as it
seems to us the single biggest deficiency with SG. We tried DG once
because of that issue but couldn't use it because it doesn't support
multiple levels of filtering - or didn't at that time. Administration
has declared different levels of filtering for admin, high school,
middle school, and elementary school here so one size doesn't fit all.
