The Network Information Center (NIC), also known as InterNIC from 1993 until 1998, was the organization primarily responsible for Domain Name System (DNS) domain name allocations and X.500 directory services. From its inception in 1972 until October 1, 1991, it was run by the Stanford Research Institute, now known as SRI International, and led by Jake Feinler. From October 1991 until September 18, 1998, it was run by Network Solutions. Thereafter, the responsibility was assumed by the Internet Corporation for Assigned Names and Numbers (ICANN).

It was accessed through the domain name internic.net, with email, FTP and World Wide Web services run at various times by SRI, Network Solutions, Inc., and AT&T. This website is still active today, operated by ICANN, and currently provides reference documents and information related to domain registration. The InterNIC also coordinated the IP address space, including performing IP address management for North America prior to the formation of ARIN. InterNIC is a registered service mark of the U.S. Department of Commerce. The use of the term is licensed to the Internet Corporation for Assigned Names and Numbers (ICANN).
