When a user requests a website, their computer contacts a DNS server to look up the website’s IP address. DNS servers use a variety of requests to lookup website addresses.
Two common types of DNS requests are A records and PTR records.
An A record is a request for the IP address for a specific hostname. For example, if a user requests www.google.com, their computer contacts a DNS server and asks for the IP address for google.
com. The DNS server responds with an A record that points to the IP address of google.com.
A PTR record is a request for the IP address for a specific hostname and its pointer, or alias, IP address.com and the IP address for 74.125.
127.98. The DNS server responds with a PTR record that points to 74.127.

What Are the Two Types of DNS Server?
There are two types of DNS servers: forwarders and resolvers. A forwarder is a DNS server that acts as a middleman and transfers requests from clients to the correct DNS servers. A resolver, on the other hand, is responsible for resolving domain names and providing IP addresses. .
What Are the Four Types of DNS Server?
DNS server types can be classified according to the way they store and serve DNS data. In RAM-based DNS servers, the data is stored in a single location on the server. The DNS server can access the data instantly, which is helpful for quickly resolving DNS queries.
What Is DNS Server and Its Types?
DNS server is a computer system that stores the mapping of domain names to IP addresses. When you type a domain name into your web browser, your computer queries a DNS server for the corresponding IP address. There are two main types of DNS servers: primary and secondary.
What Are the Services Provided by DNS Server?
A Domain Name System (DNS) server is a server that provides the corresponding Domain Name System (DNS) resource records for a particular hostname. A DNS server maintains a database of hostnames and their corresponding IP addresses, and provides the service of translating hostnames to IP addresses when requested by a client. DNS servers can also be used to obtain information about hostnames, such as the corresponding IP address or the type of service provided by a host.
What Type of Packet Is Sent to DNS Server?
When you type in a website address into your web browser, your computer consults a Domain Name Service (DNS) server to translate the website address into an IP address. (IP addresses are a series of numbers that identify each device on a network.)
DNS servers are used by ISPs, businesses, and individuals to translate domain names, such as google.com, into IP addresses. When you type in a website address, your computer sends a request to the DNS server for the translation. The DNS server then looks up the corresponding IP address in its database.

A DNS server maintains a database of these names and coordinates the translation of requests for addresses to the appropriate servers.
What Is DNS Server For?
DNS servers are essential for online communications. They are responsible for translating human-readable domain names like “www. google.com” into the numerical IP addresses that computers use to communicate with each other.
