Paul V. Mockapetris (born 1948 in Boston, Massachusetts, US) is an American computer scientist and Internet pioneer, who invented the Internet Domain Name System (DNS).

Contents

Education

Mockapetris graduated from the Boston Latin School in 1966, received his bachelor's degrees in physics and electrical engineering from the Massachusetts Institute of Technology in 1971 and his doctorate in information and computer science from the University of California at Irvine in 1982. [1] [2]

Career

In 1983, he proposed a Domain Name System architecture in RFC 882 and RFC 883. He had recognized the problem in the early Internet (then ARPAnet) of holding name to address translations in a single table on the hosts file of an operating system. Instead he proposed a distributed and dynamic DNS database: essentially DNS as it exists today. [1] [2]

The Domain Name System (DNS) is the hierarchical and decentralized naming system used to identify computers reachable through the Internet or other Internet Protocol (IP) networks. The resource records contained in the DNS associate domain names with other forms of information. These are most commonly used to map human-friendly domain names to the numerical IP addresses computers need to locate services and devices using the underlying network protocols, but have been extended over time to perform many other functions as well. The Domain Name System has been an essential component of the functionality of the Internet since 1985.

A name server refers to the server component of the Domain Name System (DNS), one of the two principal namespaces of the Internet. The most important function of DNS servers is the translation (resolution) of human-memorable domain names (example.com) and hostnames into the corresponding numeric Internet Protocol (IP) addresses (93.184.216.34), the second principal name space of the Internet, which is used to identify and locate computer systems and resources on the Internet.

A Canonical Name record is a type of resource record in the Domain Name System (DNS) that maps one domain name to another.

Fully qualified domain name

A fully qualified domain name (FQDN), sometimes also referred to as an absolute domain name, is a domain name that specifies its exact location in the tree hierarchy of the Domain Name System (DNS). It specifies all domain levels, including the top-level domain and the root zone. A fully qualified domain name is distinguished by its lack of ambiguity in terms of DNS zone location in the hierarchy of DNS labels: it can be interpreted only in one way.

In the Domain Name System (DNS) hierarchy, a subdomain is a domain that is a part of another (main) domain. For example, if a domain offered an online store as part of their website example.com, it might use the subdomain shop.example.com.

The domain name arpa is a top-level domain (TLD) in the Domain Name System (DNS) of the Internet. It is used predominantly for the management of technical network infrastructure. Prominent among such functions are the subdomains in-addr.arpa and ip6.arpa, which provide namespaces for reverse DNS lookup of IPv4 and IPv6 addresses, respectively.

Van Jacobson is an American computer scientist, renowned for his work on TCP/IP network performance and scaling. He is one of the primary contributors to the TCP/IP protocol stack—the technological foundation of today’s Internet. Since 2013, Jacobson is an adjunct professor at the University of California, Los Angeles (UCLA) working on Named Data Networking.

In computer networking, the multicast DNS (mDNS) protocol resolves hostnames to IP addresses within small networks that do not include a local name server. It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name Service (DNS). It was designed to work as either a stand-alone protocol or compatibly with standard DNS servers. It uses IP multicast User Datagram Protocol (UDP) packets, and is implemented by the Apple Bonjour and open source Avahi software packages, included in most Linux distributions. Although the Windows 10 implementation was limited to discovering networked printers, subsequent releases resolved hostnames as well. mDNS can work in conjunction with DNS Service Discovery (DNS-SD), a companion zero-configuration networking technique specified separately in RFC 6763.

Extension Mechanisms for DNS (EDNS) is a specification for expanding the size of several parameters of the Domain Name System (DNS) protocol which had size restrictions that the Internet engineering community deemed too limited for increasing functionality of the protocol. The first set of extensions was published in 1999 by the Internet Engineering Task Force as RFC 2671, also known as EDNS0 which was updated by RFC 6891 in 2013 changing abbreviation slightly to EDNS(0).
