The ability to change your IP address is probably one of the most useful tools you can have online. You can bypass filters and restrictions and the increasing number of geo-blocks, based on your location. However there are a few different methods to achieving this and indeed there's a host of companies who provide an online IP changer which you can use to switch addresses.
Watch British TV from anywhere in the world, access Hulu, HBO and Pandora from outside the USA. It's all possible if you have the possibility to change your IP address. Remember to ensure that you change your public or external IP address as it's this one which affects what you can do online. This address is assigned when you connect to the internet usually from your ISP or whichever access point you are using. The difficulty is that you cannot actually change this IP address merely 'hide' it using VPns and proxies.
