Use a VPN Service
VPN services allow you to hide your IP address from prying eyes. If you live in Montana and use a VPN server in Atlanta to connect to Twitter, for example, Twitter will only see the IP address of the VPN server in Atlanta. Your true location will remain known only to you and to the company that runs the VPN service.
In addition to hiding your IP address, VPN’s also encrypt your Internet traffic. This protects your privacy from hackers, ISP employees, or government agencies who may be “listening” to Internet traffic.
There are a few more good reasons to use a VPN, and they’re pretty easy and inexpensive to obtain and set up as well as fast enough that you likely wont even notice you’re on a VPN most of the time.
