This serves as another "tool for the job" example. The sort in *nux is as simple as: sort -n -t . -k 1,1 -k 2,2 -k 3,3 -k 4,4 ipaddress.file How easy is that ?. Even OMVS has sort that should handle that.
For the real output required, I'd pipe the output of that to gawk and use an associative array indexed on the first three octets of the IP address. Looks like the OMVS awk is missing the GNU extension of match() to use an array for splitting the IP address, but that can be worked around. REXX ? phooey.
