The most visible, and most contentious, component of the Internet transition was the registration of domain names.
Domain name registration associates a human-readable character string (such as “nsf.gov”) with Internet Protocol (IP) addresses, which computers use to locate one another.
NSF continues to support many research projects to develop new networking tools, educational uses of the Internet and network-based applications.
Previously, NSF had subsidized the cost of registering all domain names.
At the same time, the number of Internet-connected computers grew from 2,000 in 1985 to more than 2 million in 1993.
To handle the increasing data traffic, the NSFNET backbone became the first national 45-megabits-per-second Internet network in 1991.
NSF has also been instrumental in providing international connections services that have bridged the U. network infrastructure with countries and regions including Europe, Mongolia, Africa, Latin America, Russia and the Pacific Rim.
In addition, NSF has continued to extend the reach of the highest-performance U. research and education networks by supporting connectivity and collaborations with their counterparts in Canada, Europe and Asia.
