About IP addresses

Every website you visit can see quite a lot of information about you. You don't need to worry, as it's part of how the internet functions - a website needs to be able to identify your computer from others, in order to be able to reply with the information you want.

Websites identify you using your IP address - an identifying number unique to your internet connection at any one moment in time, assigned to you by your Internet Service Provider (ISP). Unless you have an agreeement with your ISP to keep a static IP address, it may change occasionally. This won't affect your internet connection, but may affect services set up to a static IP address, such as a server's firewall.

As well as your IP address, website operators also know the version of browser you're using. This allows website operators to record browser usage statistics, and ensure their website is compatible through all of it's visitors browsers. The referring website, if applicable, is also passed to the website's server, allowing the owner to see where you've arrived from, or the search term used to find the website in a search engine.
