Added ICP-3 and some additional curation of links
public suffix list is an attempt to build a database of top- level domains and their respective registry's policies on domain registrations at different levels.
Previously, browsers used an algorithm which basically only denied setting wide-ranging cookies for top-level domains with no dots (e.g. com or org). However, this did not work for top-level domains where only third-level registrations are allowed (e.g. co.uk). In these cases, websites could set a cookie for co.uk which will be passed onto every website registered under co.uk.
== Website ==
The website for the Public Suffix List is at http://publicsuffix.org/.
== Registries ==
Maintaining an up-to-date list of all top-level domains and policies is clearly a vast task, and therefore each registry has been asked to maintain their own section of the database and email any changes to the effective TLD list maintenance team, who will then merge it with the master database.
