I think my Cable Modems IP address has been blocked by an e-mail server and I need to know where I can find out what my IP address is and if it can be changed by me?
www.ipchicken.com will show your IP address
Port 25 outgoing will be blocked if you are using a dynamic IP address as well (how are you trying to communicate with this email server or what are you trying to do).
If you need to change your IP address, you need to change your MAC address, it is a slightly complicated task, so not something I would recomend trying
