[LinuxUsers] Dynamic Public ip readdressing ......

[Peter Manis]

I've heard mention that the ifup scripts will be run when DHCP updates the
dynamic address, but I have never checked.  If it does that might be a good
place to put the code.  Otherwise using grep/awk on the ifconfig output and
then comparing that to a file would work.  If the IP is not the same, update
hosts, and then update the file you are comparing against.
