What is DNS server? It is a global distributed database that maps numerical Internet protocol addresses to hostnames. DNS server is a service provided by hosts on the internet. DNS Server is the component responsible for mapping the machine name to its IP address. It is one of the primary components used in the Internet ecosystem. The Internet hosts use DNS to map the destination addresses to host names. For example, when you surf the web and type myhost.com or sub.domain.com you are actually contacting a DNS server that is closest to your machine and asks what is my hostname.

Let us see some examples of use cases: You connect to a wireless network and type wlan0.local into your browser. This hostname is resolved by local DNS server. Your DHCP client sends a request to your network card (eth0) asking what's the address of wlan0. Eth0 contacts the network server to get the host address. After a little bit, the network server replies with an address for wlan0. This resolves the hostname on the internet.

Nslookup is the program that can be used to look up the address of any hostname or domain name on the internet. Nslookup has the ability to resolve any domain name, local hosts and other types of DNS information. It can be installed via the package manager and as a software dependency. You need to have root privileges or be the super user to run the command.

But after installation when I try to open its says that is not an application . What to do? I am new in linux. Please help me to solve my problem. How can I install nslookup?

Hello,I have been trying to figure out this problem for some time now,so I have not gone on too much about this problem. First, i'll go into a little background into a lot of detail.i bought this laptop a few years ago(2004ish) because it had windows 98 installed on it (i couldn't afford to use xp)so the thing im getting at is installed a lot of software from various sites that people asked if I have any problems they said no,all programs installed and works fine(mostly).So I did that when I got it I went to a friend who told me he could use a couple programs on his laptop so I asked him if I could install something on my laptop while he's using it without any problems so installed a couple applications on his laptop and since I couldn't open them after installing them I started looking for answers on the internet then I found a lot of info that they had made updates to that programs so I downloaded the updates but I still can't open those programs so I found out it wasn't a problem with the programs the updates on those programs and tried to upgrade my nscd but that was a error I got which made me think the problem was with the nscd or if it's even possible a network interface.then later on I looked on nscd and it seems like I don't have it there but when I did type sudo apt-get install nscd but the command didn't install anything so I was wondering if the problem may be a dpkg.So any ideas are much appreciated.thanks in advance

There should be an /etc/init.d/nscd script (at least it was on older RHEL systems). That script will install nscd for you on the next reboot.
