As I and others have indicated, from the LAN side you can determine this by logging in to your router/modem. From the WAN/internet side, you WILL need another resource unless you have a static IP from your ISP. >What is stopping these websitesusing the IP number for a >malicious purpose? What is stopping *your_ISP* from doing that? With your level of paranoia I'm surprised you trust *them*.

I suppose one quick way of determining your public IP might be to send yourself an email using your isp's mail server and see if your public IP is displayed in the properties of the email. Mine is. Also my ISP displays the users public IP in the member details area of their website (requires login) as a result of member requests.

He appears to want to be able to get the IP of others, so he can remotely desktop manage THEIR systems, presumably for maintenance etc even tho the first sentence of his does say his external IP. > As others have pointed out: if the knowledge of your IP address > exposes you to malicious purposes, your system lacks fundamental > safeguards.
