What is DNS and how it works? -Network admin interview
DNS stands for Domain name system and it translates (converts) the host name into the IP address and IP address into to the host name. Every domain and the computer on the internet is assigned a unique IP address. The communication on the internet and in the network is based on the IP addresses. IP addresses are in this format,, etc. IP addresses can’t be remembered but the host names are easy to remember instead of their IP addresses.
