That is indeed awesome. Although, you could optimize it by moving the
sort after the awk, since it looks like httpd has lots of different
pids accessing the same inode. I'm squirreling it away.

Given a ip1.txt, a text file that has a list of ip addresses in it,
the following will put them in order:

awk -F. '{print $1*65536+$2*256+$3 " " $0}' ip1.txt | sort -n | cut -f
2- -d ' ' > sorted.txt
