The ISP issues an dynamic ip address which has not changed in 12 years. My host has 2 NICs, one which is not used. I know if I plug the internet cable into the un-used NIC and make the appropriate config changes and reboot I will get a different dynamic ip address. Is there a simpler way to expire the lease to force the ISP dhcp to refresh with a different dynamic ip address? The goal is to have a cron job that gets a different dynamic ip address assigned to my host's front door every a week. Just another level of security to make it very hard for the script kiddies from finding any open ports I may have. Thanks for the help.
