The 1.1.1.1 DNS service operates recursive name servers for public use at the twelve IP addresses listed below. [11] These addresses are mapped to the nearest operational server by anycast routing. [12] The DNS service is also available for Tor clients. [13] Users can set up the service by manually changing their DNS resolvers to the IP ...
The root nameservers are critical infrastructure components of the Internet, mapping domain names to IP addresses and other resource record (RR) data. Attacks against the root nameservers could, in theory, impact operation of the entire global Domain Name System, and thus all Internet services that use the global DNS, rather than just specific ...
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.

DDN-NIC or Network Information Center (NIC) was located at the DDN Installation and Integration Support (DIIS) program office in Chantilly, Virginia. It provided general reference services to DDN users via telephone, electronic mail, and U.S. mail. [8] It was the first organization responsible for the assignment of TCP/IP addresses and Autonomous System numbers.
The IP address of a public server is also important, similar in global uniqueness to a postal address or telephone number. Both IP address and port number must be correctly known by all hosts wishing to successfully communicate. Private IP addresses as described in RFC 1918 are usable only on private networks not directly connected to the internet.
The location information server, or LIS is a network node originally defined in the National Emergency Number Association i2 [1] network architecture that addresses the intermediate solution for providing e911 service for users of VoIP telephony. The LIS is the node that determines the location of the VoIP terminal.
The DoD made TCP/IP the standard communication protocol for all military computer networking in 1980. [85] NORSAR and University College London left the ARPANET and began using TCP/IP over SATNET in 1982. [86] On January 1, 1983, known as flag day, TCP/IP protocols became the standard for the ARPANET, replacing the earlier Network Control Protocol.
