Q. What is DNS?
Ans. DNS means Domain Naming Service, and it is used for resolving IP addresses to name and names to IP address. Like if you type www.google.com it will convert it into ip address something like 192.128.0.1 . You can check any websites ip via using Ping cmd (Ping www.google.com -t).

Q. How DNS works ?
Ans. In short you can tell them that when we search any website like google.com then it first checks Host file for ip address which store in C drive/windows/sytem32/etc and if it did’nt find out website ip then it move towards Resolution Cache for ip address. Resolution Cache mainly stored the ips of websites which we searched previously and if it still not able to find ip then

Local dns contacts the root domain to learn the specific domain’s ip addresses … The root domain guides local dns to check with top-level domain(TLD) such as (.com,. Org etc) by providing it’s ip address,,, and local DNS contacts, and ask TLD if it knows the ip address of a particular domain … This tld gives dns server ip address …. And local dns query dns server the same which contains all the information about the domains and ip adress then finally local dns gets the IP address from dns server
So this is how it works.

*Tips : This is the most asked question in HCL Technologies Service Desk Analyst Interview or any Service Desk interview Desktop Support Interview so be prepared.

Q. What is forward and reverse lookup in DNS?
Ans. When we convert an IP address into names it is called Reverse lookup, while converting names into IP address is called Forward lookup.

Ans. Basically A record is Host record which contain Ip address and domain name related record while, ‘MX record’ also known as mail exchanger record, by the help of ‘MX’ record, location of the mail server is identified.  The record is also found in DNS.
