Browsers may render only a URL’s host in places where it is important for users to distinguish between the host and other parts of the URL such as the path. Browsers may consider simplifying the host further to draw attention to its registrable domain. For example, browsers may omit a leading www or m domain label to simplify the host, or display its registrable domain only to remove spoofing opportunities posted by subdomains (e.g.,
https://examplecorp.attacker.com/).
