The Palestinian National Internet Naming Authority (PNINA) is the Official domain registry for the Palestinian country code Top-Level-Domain (ccTLD).

PNINA’s implementation plan was initiated in early 2003. PNINA’s role is to realize the Palestinian on-line presence through the formulation of registration policies, administer the .ps domain Registry, and to enhance and promote Internet usage in Palestine.

Early 2011 PNINA launched Palestinian country code Top-Level-Domain in Arabic which known as ( فلسطين .). It is possible now to reach the websites by using the pure Arabic domain names in Arabic characters.
