Doug, one of our readers, can no longer send email from his computer. After some troubleshooting, he has isolated the problem. “Turns out that my IP address has been blacklisted, but not my fault. The ipconfig /release and renew commands do not change the IP address.” “Are these the only ways to get a new IP address, being 1) get a static address, 2) shut down the network for a week or 72 hours, or 3) change ISPs?” Is there any better solution to Doug’s problem? → Discuss – Changing Your Public IP Address → See also – How to Change Your IP Address DISCUSS: Changing Your Public IP Address originally appeared on About.com Wireless / Networking on Monday, February 1st, 2010 at 01:55:01.
