If you've ever wondered where on earth a website you were visiting was located, you've come to the right place. Perhaps you were curious where that email with the strange country extension originated. While most folks recognize that .uk is the United Kingdom, .ca is Canada, .ru is Russia, .jp is Japan, and .au is Australia, many of the other internet country codes are downright perplexing.

Each country code top-level domain (ccTLD) is a top-level domain used and reserved for a specific country or a dependent territory. Understand that some countries allow anyone in the world to register domain names in their ccTLD, while others have strict rules specifically forbidding anyone other than residents from acquiring a domain with their internet country code. So, even if you know the country extension of a Web site or email, it's not always a guarantee that the site or email is actually located in, or originated from, that country.

If you examine server logs to monitor traffic trends, or merely examine your website logs to see where your visitors reside, you should also find the following alphabetical listing of two-letter country code top-level domain extensions helpful.

* NOTE: In 2007, the Internet's key oversight agency, ICANN (Internet Corporation for Assigned Names and Numbers), announced it was eliminating the ".um" domain.
