That sounds fun!

Well, basically you need a structure of nested Hashes.  Matching would
start at the TLD and descend to the most specific domain.

That's certainly faster if memory is sufficient for the size of lists
you want to handle.

Why?

irb(main):020:0> "foo.bar.baz".split(/\./).reverse
=> ["baz", "bar", "foo"]
irb(main):021:0> "foo.bar.baz".split(/\./).reverse.join('.')
=> "baz.bar.foo"

Well, if you make "allow" and "deny" (or only "deny") a category then
it's just one mechanism. :-)

Order in table rarely matters with RDBMS.  It's the indexes which are important.

Isn't it more important that the UI presents human readable
information?  But I agree, readable DB contents helps in debugging
etc.  That's why I suggested the reversed format based on domains.

I'd be careful with that.  That philosophy only works for small
systems where it is easy to do a major rewrite.  In other cases it
might bring you into a situation where you are stuck with an
architecture that does not fit the needs.
