INFORMATION

A host file is used for mapping an IP address to a domain. it works as a DNS resolver for your own system, it doesn’t require internet to connect to a DNS server for knowing the IP-address for a website.

you can also use it to redirect someone to your website in your network.
for an example: your Local IP is 192.168.43.183 now we will edit host file and type facebook.com google.com and we will add our IP before it. And whenever we will try to visit google.com or facebook.com, we will be redirected to our local IP.

CONFIGURATION

In Windows,

you will find the hosts file in windows in c:\windows\system32\drivers\etc\hosts

it will look like this :

In Linux(Debian, Ubuntu) and MAC os,

you will find the hosts file in Linux operating system in /etc/hosts

type this command to open the hosts file:

now, run the apache server with this command:

service apache2 start

after running it, go to the browser and visit: technicalnitesh.com
