The Public Suffix List is a catalog of

certain Internet domain names. The term is also known by the form effective top-level domain (eTLD).[1]

The Mozilla Foundation maintains suffix list for the security and privacy policies of its Firefox web browser, though it is available for other uses under the Mozilla Public License (MPL).

List

The list is used by Mozilla browsers (Firefox), by Google in Chrome and Chromium projects on certain platforms,[2]) and by Opera.[3] Future{{which|date=May 2017}} versions of Internet Explorer will also use the list.[4]

According to Mozilla,[5]

{{quote|A "public suffix" is one under which Internet users can directly register names. Some examples of public suffixes are ".com", ".co.uk" and "pvt.k12.wy.us".}}

While com, uk, and us are top-level domains (TLDs), Internet users cannot always register the next level of domain, such as "co.uk" or "wy.us", because these may be controlled by domain registrars. By contrast, users can register second level domains within com, such as example.com, because registrars control only the top level. The Public Suffix List is intended to enumerate all domain suffixes controlled by registrars.[6]

Some uses for the list are:

  • Avoiding "supercookies", HTTP cookies set for high-level domain name suffixes. In other words, a page at foo.example.co.uk might normally have access to cookies at bar.example.co.uk, but example.co.uk should be walled off from cookies at example2.co.uk, since the latter two domains could be registered by different owners.
  • Finding DMARC policy records for email subdomains.
  • Highlighting the most important part of a domain name in the user interface.
  • Improving the sorting of browser history entries by site.

It contains a list of points in the hierarchical namespace at which registrations take place, and is used to identify the boundary between so-called "public" names (below which registrations can occur, such as ".com" or ".org.uk") and the private names (organizational names) that domain registrars create within them.}}
