WWW2 and WWW3 are hostnames or subdomains, typically used to identify a series of closely related websites within a domain, such as www.example.org, www2.example.org, and www3.example.org; the series may be continued with additional numbers: WWW4, WWW5, WWW6 etc. Traditionally, such websites are mirrors used for server load balancing. In some cases, the specific hostname may be obscured, creating the appearance that the user is viewing the "www" subdomain, even if they are actually viewing a mirror site.

WWW2 or WWW3 may also refer to:

  • Subdomain, part of a domain name identifying a website
  • World Wide Web, a system of interlinked, hypertext documents that runs over the Internet
