DNS is a directory service that maps a host&#8217;s name to its numerical address on a network. DNS is necessary for the internet to function. <\/p>\n\n\n\n<p>A domain name is a sequence of symbols specified by dots that are assigned to each node in a tree. The Domain Name System (DNS) is a service that converts domain names into IP addresses. This allows network users to search for other hosts using user-friendly names rather than knowing IP addresses.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Working of DNS<\/strong><\/h2>\n\n\n\n<ol class=\"wp-block-list\"><li>DNS is a network communication mechanism for clients and servers. DNS clients make requests to DNS servers, and DNS servers respond to the queries.<\/li><li>Forward DNS lookups are queries that contain a name that is turned into an IP address, whereas reverse DNS lookups are requests that contain an IP address that is transformed into a name.&nbsp;<\/li><li>DNS uses a distributed database to keep track of the names of all the hosts on the internet.<\/li><li>A piece of software such as DNS resolver sends a request to the DNS server to acquire the IP address of a hostname when a client such as a web browser submits a request containing a hostname. If a DNS server does not have the IP address for a hostname, the request is sent to another DNS server. If the resolver receives an IP address, it completes the request over the internet protocol.<\/li><\/ol>\n\n\n\n<p>Interested in learning about similar topics?
