The most basic function of a DNS server is to translate a domain name into its respective IP address.

What is the main purpose of a DNS server?

Domain Name Servers (DNS) are the Internet’s equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.

What layer is DNS?

In OSI stack terms, DNS runs in parallel to HTTP in the Application Layer (layer 7). DNS is in effect an application that is invoked to help out the HTTP application, and therefore does not sit “below” HTTP in the OSI stack. DNS itself also makes use of UDP and more rarely TCP, both of which in turn use IP.

How do I find out what my DNS server is?

Type or paste the “ipconfig /all” command (without the quotation marks) into the Command Prompt and press “Enter” to run it and get detailed information about the network. Locate the IP address of the computer in the “IPv4 Address” field. Locate the primary DNS IP address in the “DNS Servers” field.

What is DNS and its types?

What are the different types of DNS server? All DNS servers fall into one of four categories: Recursive resolvers, root nameservers, TLD nameservers, and authoritative nameservers.

How do you refresh DNS?

  1. WinXP: Start, Run and then type “cmd” and press Enter.
  2. Vista, Window 7 and Windows 8: Click “Start” and type the word “Command” in the Start search field.
