The collection of host-name-to-IP-address mappings contained with the DNS database is also known as a namespace. Essentially, when looking for a name in DNS, the DNS client first checks a top-level DNS server database. That server tells the client which DNS server hosts the next part of the DNS name, and the client then queries that server.
Because of this, every DNS resolver has a list of the 13 IP root server addresses built into its software. Whenever a DNS lookup is initiated, the recursor’s first communication is with one of those 13 IP addresses. What happens if a DNS root server becomes unavailable? Domain Name System (DNS) is a standard by which names used on the Internet are resolved to their corresponding IP addresses. A DNS hostname is a name that uniquely and absolutely names a computer; it's composed of a host name and a domain name. What is a "DNS leaks"? In this context, with "DNS leak" we mean an unencrypted DNS query sent by your system OUTSIDE the established VPN tunnel. Why my system suffers DNS leaks? In brief: Windows lacks the concept of global DNS. Each network interface can have its own DNS. There are billions of IP addresses currently in use, and most machines have a human-readable name as well. DNS servers (cumulatively) are processing billions of requests across the internet at any given time. Millions of people are adding and changing domain names and IP addresses each day.
The GetHostAddresses method queries the DNS subsystem for the IP addresses associated with a host name. If hostNameOrAddress is an IP address, this address is returned without querying the DNS server. If an empty string is passed as the hostNameOrAddress argument, then this method returns the IPv4 and IPv6 addresses of the local host.

The DNS (Domain name system) server converts the Domain names (example – techworm.net) to Equivalent IP addresses (such as 192.168.1.1). IP addresses are similar like our home addresses. For example, If someone wants to visit us then they need to follow the right address in order to reach us.
