DNS stands for Domain Name System, which, at its most basic, works like the phone book for the internet. You can think of DNS like your smartphone’s contact list, which matches contact’s names with their phone numbers and email addresses.
DNS is a hierarchical host naming system connected to the internet or any private network. The process involves converting the domain names of participating entities or hosts to a computer-friendly IP address.
DNS has been one of the foundations of the functionality of the internet since 1985. Though we don’t realise it, we use DNS to check our emails or while browsing on our smartphones every day. Whenever you connect to the internet, the DNS server that you use is automatically established by your network provider.
