CCSO Nameserver
open-in-new
<p>A CCSO name-server or Ph protocol was an early form of database search on the Internet. In its most common form, it was used to look up information such as <a href="/facts/Telephone_number/Px4q5qFo">telephone numbers</a> and <a href="/facts/Email_address/srdpG6am">email addresses</a>. Today, this service has been largely replaced by <a href="/facts/Lightweight_Directory_Access_Protocol/KgpfD8nR">LDAP</a>. It was used mainly in the early-to-middle 1990s. The name-server was developed by <a href="/facts/Steve_Dorner/vlvhWWfj">Steve Dorner</a> at the <a href="/facts/University_of_Illinois_at_Urbana%E2%80%93Champaign/gusw7HoS">University of Illinois at Urbana–Champaign</a>, at the university's Computing and Communications Services Office (CCSO). </p><p>There also exists an Outlook plugin and <a href="/facts/Standalone_program/2KduaAxh">standalone application</a> known as OutlookPH. </p>
