Nameserver is a server that handles queries regarding the location of a domain name’s various services such as website, emails and so on.
Thankfully, today there is a lot of redundancy built into DNS. For example, there are many instances of the root DNS servers and TLD nameservers, and most ISPs have backup recursive resolvers for their users. (Individual users can also use public DNS resolvers, like Cloudflare’s 1.1.1.1...

A Domain Name System (DNS) leak occurs when DNS requests are sent to an internet service provider (ISP) even when a virtual private network (VPN) is being used to encrypt browsing activity.
The DNS query process When you enter a domain name (e.g., www.example.com) into your web browser, a series of steps is triggered to resolve this domain name into an IP address: Step 1: User’s request User action: You type the domain name into your browser and press enter. ...
Reverse DNS (rDNS) is a process that determines the domain name associated with a specific IP address. Simply put, reverse DNS allows you to identify a domain name, likephoenixnap.com, from its IP address, such as198.15.93.98. Resolving an IP address back to its domain name improves the ...
DNS delegation is the process of dividing up the DNS namespace into one or more zones. A delegation signer (DS) record is a hashed “fingerprint” of the public DNSKEY, stored in the parent zone. When a resolver tries to access records from a child zone, it verifies the public DNSKEY...
