The DNS Client can then communicate with home_server. The DNS Server replies with the IP address of home_server ( DNS Reply). Since the DNC Client doesn’t know the IP address of home_server, it sends a DNS Request to the DNS Server, asking for the IP address of home_server. The user’s browser is then able to access using that IP address.ĭNS Client wants to communicate with the server named home_server. The DNS server then replies with the IP address. When a user request some network resource using a hostname, (for example, by typing in a browser), a DNS request is sent to the DNS server asking for the IP address of the hostname. The application maintains a table of dynamic or static hostname-to-IP address mappings. A DNS server has a special-purpose application installed.
To use DNS, you must have a DNS server configured to handle the resolution process.
You can access the Google homepage by typing 74.125.227.99, but it’s much easier just to type let DNS do the translation. If another public DNS server is used, both addresses need to be changed accordingly in order to comply. DNS is not required to establish a network connection, but it is much more user friendly for users than the numeric addressing scheme. The DNS server addresses, 8.8.8.8 and 8.8.4.4, are the addresses of Google’s public DNS servers. DNS (Domain Name System) is a network protocol used to translate hostnames into IP addresses.
