What is DNS?

DNS


A domain name system is a hierarchical and distributed naming system used to identify computers that can be accessed through the internet or other internet protocol networks. Resource records located in DNS associate domain names with other forms of information. These names are most commonly used to assign human-friendly domain names to digital IP addresses that computers need to locate services and devices using basic 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 internet functionality since 1985.

Function


An often used analogy to explain the DNS is that it acts as a telephone directory for the internet by translating human-friendly computer hostnames into IP addresses. For example, the domain name translates www.example.com to the addresses and. DNS can be updated quickly and transparently, which allows changing the location of the service on the network without affecting end users, who continue to use the same hostname. Users benefit from this when they use meaningful unified resource locators and email addresses without having to figure out how the computer actually located the services.

One of the important and ubiquitous functions of the DNS is its central role in distributed internet services such as cloud services and content delivery networks. When a user accesses a distributed internet service using an URL address, the URL address domain name is translated to the IP address of a server nearby the user. The main function of the exploited DNS here is that different users can simultaneously receive different translations of the same domain name, which is a key point of difference from the traditional DNS phonebook view. This process of using DNS to assign nearby servers to users is the key to providing faster and more reliable responses on the internet and is widely used by most major internet services.
DNS reflects the structure of administrative responsibility in the internet.

History


The use of a simpler and more recognizable name instead of the digital address of the host dates back to the ARPANET era. The Stanford Research Institute kept a text file named HOSTS.TXT assigned hostnames to the digital addresses of computers on the ARPANET. Elizabeth finler developed and maintained the first ARPANET directory. The maintenance of digital addresses, called the list of assigned numbers, was handled by John Postel at the Institute of Information Sciences of the University of Southern California, whose team worked closely with SRI.

Addresses were set manually. Computers, including their host names and addresses, were added to the primary file by contacting the SRI Network Information Center, managed by Feinler, by phone during business hours. Later, finler set up a WHOIS directory on a server in NIC to retrieve information about resources, contacts and entities. She and her team developed the concept of spheres. Finler suggested that the domains be based on the location of the physical address of the computer. For example, computers in educational institutions will have an edu field. She and her team ran the host naming registry from 1972 to 1989.

  By the early 1980s, maintaining a single centralized host schedule had become slow and impractical, and the emerging network required an automated naming system to address technical and personnel issues. Postel managed the task of finding a compromise between five competing proposals for solutions for Paul Mockapetris. Instead, Mockapetris created the domain name system in 1983 while at the University of Southern California. 

The Internet Engineering Task Force published the original specifications in RFC 882 and RFC 883 in November 1983. It was updated in RFC 973 in January 1986.
In 1984, four UC Berkeley students, Douglas Terry, Mark painter, David Riegel, and songnian Zhu, wrote the first Unix name server application for the Berkeley internet domain name, commonly referred to as BIND. In 1985, Kevin Dunlap from DEC significantly revised the DNS implementation. Then Mike Karls Almquist and Paul Fixi took over the maintenance of BIND. The internet systems consortium was founded in 1994 by Rick Adams, Paul fixie and Carl Malamud, expressly to provide a home for the development and maintenance of BIND. BIND versions from 4.9.3 onwards are developed and maintained by ISC, with the support of ISC sponsors. As co-architects / programmers, Bob Haley and Paul fixie released the first production-ready version of Version 8 of BIND in May 1997. Since 2000, more than 43 different core developers have worked on BIND.
 
In November 1987, RFC 1034 and RFC 1035 replaced the 1983 DNS specification. Several additional RFCs suggested extensions to the basic DNS Protocols.

Google public DNS


Google Public DNS is a domain name system (DNS) service provided by Google to internet users around the world. It works as a recurring nameserver. Google public domain name system was announced on December 3, 2009, [1] in an effort described as "making the web faster and more secure". As of 2018, it is the largest public DNS service in the world, handling more than a trillion queries per day.  Google public domain name system is not associated with Google Cloud DNS, a domain name system hosting service.

Google Fiber DNS


To Configure dynamic DNS for Google fiber DNS:

Sign in to Google Fiber using the email and password you use for your account.
Select Network at the top-left corner.

  • In the settings pane, click Advanced; then click DNS.
  • Dynamic DNS
  • The Google Fiber network assigns IP addresses to devices when they connect. These IP addresses are generally unpredictable and subject to change. If you want to host a service such as FTP or SSH on your network, use the DNS advanced settings to set up Dynamic DNS for the hostname, so outside consumers of the service can still access it when your host IP address changes.

To configure Dynamic DNS:

  1. Select the name of your Dynamic DNS provider from the Service provider drop-down menu.
  2. Enter or modify the username for your Dynamic DNS account.
  3. Enter or modify the password for your Dynamic DNS account.
  4. Enter the domain or hostname for the service you want to host.
  5. Click Apply.

To stop using the Dynamic DNS service:

Select None for Service in the Dynamic DNS section of the DNS tab.
Click Apply.

DNS name resolution


When an outgoing request is sent from your network, the Network Box must find the IP address that corresponds to the domain name in the request. It contacts a DNS server to do this. If the DNS server does not know the mapping, the Network Box contacts the next DNS server in the hierarchy, and so on, until an IP address is found or the Network Box has checked all DNS servers in its list.
By default, the Network Box uses DNS servers specified by Google, but you can override this.

To use Google-selected DNS servers for name resolution:
  • Click Automatic for DNS servers.
    • Click Apply to start using Google-selected DNS servers.

To specify custom DNS servers to use for name resolution:
  • Select Custom for DNS Servers.
  • Enter the IP addresses of up to three DNS servers in the DNS server fields, in the order in which you want the Network Box to contact; then click Apply.

Manage DNS settings with the Google Fiber app


You can use the Google Fiber app to customize your network's DNS settings.

To manage your DNS settings:

  1. open app
  2. click Network .
  3. click Edit Network Settings
  4. click Advanced Network Settings
  5. click DNS
  6. To customize your DNS settings, tap the Define custom servers switch.
  7. Enter up to 3 DNS server addresses.
  8. To enable Dynamic DNS, use the Service Provider menu to choose a service provider.
