If that leased line is from your ISP, and not tied directly to the
backbone, then you should be able to use their DNS. All that will
require is an entry for the address of that machine.
OTOH, if the machine you run the DNS on is the only one that knows about
the rest of the world, and its secured, then the temptation to do some
'editing' of the list to remove the pruient sites becomes rather
attractive. This is, I expect, a 24 hour a day job though unless you
can find some filtering software that will do it for you *most* of the
time.
Note that this will not prevent some determined individual from bringing
the numerical address in and useing it to bypass your efforts. Blocking
that is another area, requiring a numerical blacklist and its
maintainance.
#include <std.disclamer> cause I haven't the foggiest how to do all that!
Cheers, Gene
