the forwarder of an ISP can have a huge cache which can speed up resolving
of frewquently used names. It also can have configured local reverse and
direct domains that speeds up their resolution.

It can also have local RFC 1918 and RFC 3333 (and possibly other) reverse zones that may speed up
resolution of those, since there still are many of DNS servers that do not
have them configured.

It's surprising the numbers of people who think that this is not benefit to
them....
