The ".fm" at the end of a web address is the country code for the Federated States of Micronesia. However, anyone can obtain an Internet domain name ending in ".fm," so radio broadcasting companies that have nothing to do with Micronesia often use it in their domain names.
Each country has a two-letter country code for the end of website addresses originating in that country. This is known as the country code top-level domain. In a web address such as www.mysite.com, "mysite" is the domain name and ".com" is the top-level domain. Instead of ".com," a country code might be used. For example, the web address of the America's National Parks is www.Parks.US, where ".US" stands for United States.
