Sets hops for IPv4 loose source routing. You can use -g
once with a comma-separated list of hops, use -g multiple
times with single hops to build the list, or combine the two. Hops can be
given as IP addresses or hostnames.
-G <ptr> (Set source routing pointer)
Sets the IPv4 source route “pointer” for use with -g.
The argument must be a multiple of 4 and no more than 28. Not all operating
systems support setting this pointer to anything other than four.
