What is a Hosts File?

The hosts file is a local plain text file that maps servers or hostnames to IP addresses. This file has been in use since the time of ARPANET. It was the original method to resolve hostnames to a specific IP address. The hosts file is usually the first process in the domain name resolution procedure. Here is an example of a hosts file entry.

note:- We have added the curly brackets around each entry in the hosts file belwo to better define each section.

{67.225.187.61} {liquidweb.com}

We use the above code as an example since it almost always included in every hosts file. Another example would be similar to the following entry.

· The first section denotes the IP address where a request will be redirected to.

· The second section designates the location that we want to redirect a request from.

· The third section specifies a comment for the entry.

· Each entry is usually separated by a space or a tab

Why is a Hosts File Useful?

Let’s say we have just completed a migration to a new server. In order to see how our domains will look and operate on our new server before we move our DNS settings, we cannot just type in one of our current domain names as it will resolve to the old server we are moving away from (since we never move our DNS A records from the old server until we are sure the new site is working as expected).

So, to see how our domain will look on the new server, (without having to change our DNS record ) we can simply modify our local hosts file to point the domain to the new servers IP. If our domain is liquidweb.com and the old IP is 67.225.187.61 and our new IP will be 72.30.35.10, we can temporarily comment out the current liquidweb.com entry (using a ‘#’ symbol) and add an alternate entry which points to the new servers IP.

#67.225.187.61 liquidweb.com #Liquid Web72.30.35.10   liquidweb.com #this is the new liquidweb.com

If we added the above entry to our hosts file, every time we open liquidweb.com in our browser, we will now be redirected to the 72.30.35.10 IP.

Where is the Hosts File Located?

The location of the hosts file will differ by operating system. The typical locations are noted below.

Windows 10 — “C:\Windows\System32\drivers\etc\hosts”

Linux — “/etc/hosts”

Mac OS X — “/private/etc/hosts”
