Domain name system (DNS) is a hierarchical database of all the hostnames and IP addresses in a domain. When a user requests a website, their computer looks up the website’s hostname (for example, www.google.com) in DNS.
If the computer can’t find the website’s hostname in DNS, the computer will look up the website’s IP address (for example, 173.194.233.222).
DNS is important for two reasons. First, it enables computers to easily find websites by their hostnames.
Second, DNS provides a way for computers to share information about websites, such as the website’s IP address and the domain name that the website is registered under. This enables websites to be easily found across different computers and networks.

What Is the Purpose of the Domain Name System DNS?
The Domain Name System (DNS) is a hierarchical, decentralized, and distributed database that provides the translation of domain names (e.g. example.com) to IP addresses. DNS was originally developed as a project of the United States Defense Advanced Research Projects Agency (DARPA) in the early 1990s.
What Is the Purpose of Domain Name System DNS?
DNS (Domain Name System) is a hierarchical naming system for computers, phones, and other devices. It converts human-readable names (like www.example. com) into numeric IP addresses.
How Does a DNS Domain Work?
DNS is the Domain Name System, which helps computers find the right web page by translating human-readable domain names like “www.google. com” into numerical IP addresses. When you type in the domain name for a website, your computer queries DNS for the corresponding IP address.
What Is Local DNS Domain?
A local DNS domain is a domain name that is associated with a specific location, such as a company or an individual’s home. When a user requests a website or email address from a device, the device accesses the website or email address via the local DNS domain.
What DNS Should a Domain Controller Use?
When setting up a new domain, it is important to decide on the DNS servers that will be used. A domain controller should use the DNS servers that are registered with the domain. Additionally, the domain controller should also use the DNS server for the forest that the domain is a part of.
What DNS Should Domain Controller Use?
A DNS server should be authoritative for the domain it is serving. This means that the DNS server should have the most up-to-date information about the domain’s name servers and the records for the domain. If the DNS server is not authoritative for the domain, it may not be able to provide accurate information about the domain’s name servers and records.
What Is Domain Name System DNS and Its Purpose?
Domain name system (DNS) is a set of protocols that allows computers to easily find each other on the Internet. DNS is made up of a hierarchy of servers, each of which caches a list of domain names. When a user types a domain name into their browser, their computer queries a DNS server for the corresponding IP address.
What Is DNS Setting for Domain?
Domain Name System (DNS) is the hierarchical system used to resolve domain names to IP addresses. DNS is used to translate human-readable domain names into the numerical IP addresses used by computers. DNS is managed by a DNS server.
What Device Is Responsible for Each DNS Domain?
Domain name systems (DNS) are essential for the functioning of the internet. Each DNS domain is managed by a different type of device. The Domain Name System Security Extensions (DNSSEC) are a set of extensions to the Domain Name System (DNS) protocol to provide cryptographic security for DNS data.
