a series of characters—letters or numbers—that represents a website, such as “cfr.org.” Domains are related to, but distinct from, URLs and IP addresses. URLs are also series of characters, but they identify the location of an item on the internet; for example, if you wanted to view a specific report on cfr.org, you would type the URL “www.cfr.org/nameofreport.pdf.” IP addresses are numbers assigned to websites that domain names represent.
