This advisory examines how current operating systems and applications process
search lists. It outlines the issues related to the current search list behavior,
and proposes both a strawman to improve search list processing in the long term and
mitigation options for the Internet Corporation for Assigned Names and Numbers
(ICANN) and the Internet community to consider in the short term. The purpose of
these proposals is to help introduce new generic Top Level Domains (gTLDs) in a
secure and stable manner with minimum disruptions to currently deployed systems.
