Date: 11/01/1988In November 1988, another TLD was introduced,int. This TLD was introduced in response to NATO’s request for a domain name which adequately reflected its character as an international organization. It was also originally planned to be used for some Internet infrastructure databases, such as, the IPv6 equivalent of However, inMay 2000, the Internet Architecture Board proposed to exclude infrastructure databases from the int domain. All new databases of this type would be created in arpa (a legacy domain from the conversion of ARPANET), and existing usage would move to arpa wherever feasible, which led to the use of for IPv6reverse lookups.

1988 TCP/IP goes global In 1988 Daniel Karrenberg, from Centrum Wiskunde & Informatica (CWI) in Amsterdam, visited Ben Segal,CERN’s TCP/IP Coordinator, looking for advice about the transition of the European side of the UUCP Usenet network (much of which ran over X.25 links) over to TCP/IP. In 1987, Ben Segal had met with Len Bosack from the then still small company Cisco about purchasing some TCP/IP routers for CERN, and was able to give Karrenberg advice and forward him on to Cisco for the appropriate hardware. This expanded the European portion of the Internet across the existing UUCP networks, and in 1989 CERN opened its first external TCP/IP connections. This coincided with the creation of Réseaux IP Européens (RIPE),initially a group of IP network administrators who met regularly to carry out co-ordination work together. Later, in 1992, RIPE was formally registered as a cooperative in Amsterdam.

1988 The term “internet” was adopted in the first RFC published on the TCP protocol (RFC 675: Internet Transmission Control Program, December 1974) as an abbreviation of the term internetworking and the two terms were used interchangeably. In general, an internet was any network using TCP/IP. It was around the time when ARPANET was inter linked with NSFNETin the late 1980s, that the term was used as the name of the network, Internet, being a large and global TCP/IP network.

1988 military use In 1981 NSF supported the development ofthe Computer Science Network (CSNET). CSNET connected with ARPANET usingTCP/IP, and ran TCP/IP over X.25, but it also supported departments without sophisticated network connections, using automated dial-up mail exchange. Its experience with CSNET lead NSF to use TCP/IP when it created NSFNET, a 56kbit/s backbone established in 1986, that connected the NSF supported supercomputing centers and regional research and education networks in theUnited States. However, use of NSFNET was not limited to supercomputer users and the 56 kbit/s network quickly became overloaded. NSFNET was upgraded to 1.5Mbit/s in 1988. The existence of NSFNET and the creation of Federal Internet Exchanges (FIXes) allowed the ARPANET to be decommissioned in 1990. NSFNET was expanded and upgraded to 45 Mbit/s in 1991, and was decommissioned in 1995 when it was replaced by backbones operated by several commercial Internet Service Providers.
