The term 'Feature of Web Addresses' can be summarized as the use of a DOT (.) to separate different parts of a web address. This feature is used to identify the domain name, subdomain, and top-level domain of a website. For example, in the web address www.example.com, the DOT separates the subdomain (www) from the domain name (example) and the top-level domain (com). The DOT is an essential part of web addresses and is used to help users navigate the internet.
