This is exactly what the spec says you should do for
a group name. Read RFC 1001/1002.

An *internet* group name is a special MS invention
that returns an IP list as you require. I used this
in the recent PDC/BDC query code on NAME<1c>. Our
WINS server also supports this.

a self-assembly Space Shuttle with no instructions.
