What is DNS?

DNS stands for Domain Name System. When you access a website, you use this service to locate the server where the domain's website is. When browsing the web, you usually type in a domain name like www.google.com into your browser. This is better than trying to remember an IP address linked to a Google server.

What is Reverse DNS?

A reverse DNS lookup is a query in which a domain name connected with an IP address is returned. However, in a forward DNS lookup, an IP address is returned when the domain name is queried. The following is an example output of reverse DNS lookup.

What is a DNS Zone?

A Domain Name System (DNS) zone is the area of the DNS namespace under the control of one particular administrator or organization. A DNS zone is a space for the administration that enables more precise control over DNS elements like authoritative nameservers. The DNS root domain is at the top of a hierarchical tree representing the domain name space.

A domain is a unique Internet address for websites that is readable by humans. When working with domains and domain name system (DNS) management, it is helpful to understand what is a fully qualified domain name (FQDN). This article will help explain the concept of an FQDN and what makes up a domain name.

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.

Your domain is the most important part of your web presence. Recognizing this, the Internet Corporation for Assigned Names and Numbers (ICANN) has requirements in place that help keep domain transfers secure. Of course, following these requirements means that transferring domains takes a few more steps than you might otherwise think. Here are the steps for transferring domains to and from Liquid Web:

What is DNS?

The Domain Name Service (or DNS) is the key to the presence of your server on the internet. You are probably aware your domain has an “IP” address, which stands for Internet Protocol; that number is your domain’s literal web address on the internet. A typical IP address is a series of four numbers called octets that are identified like so: 10.10.10.10.  You can think of your IP address as being similar to a postal address. The IP address is the exact location where your domain lives. I usually explain it like this;

You may have noticed, when transferring a website, that the URL is still stuck on the old site even though you have changed the virtual host file to reflect the new domain name. Or you may see the URL entirely greyed out in your WordPress portal. This mismatch can happen if you can’t change the URL within WordPress to reflect the new site name. In this tutorial, we will show you how to change the URL through the database.
