This address contains clues about where you are physically located in world, usually narrowing it down to a specific country and city. When you open a website, store instantly looks at your IP address to pinpoint your location.

Instead of forcing you to scroll through long menus, website can automatically display text in your local language, set correct currency, and show products that are actually legal and available to ship to your country.
