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.

Troubleshooting website issues is a difficult task. You may not know where to start depending on your problems.

Managing DNS can be a daunting, but rewarding task. For those managing DNS on their server, it is vital to know how to add a record with DNS Zone Editor in cPanel. This knowledge proves necessary and helps DNS management easier.

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.

One of the most powerful tools available to anyone working on their site during a migration is their computer's "hosts" file. The hosts file is used to map domain names to IP addresses, and can be used as an alternative to DNS. It also allows you to specify the IP address to which a website resolves on your computer, regardless of what may be published in the site's DNS zone file.

What is DNS?

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

What is nmcli?

nmcli stands for Network Management Command-Line Interface, and is a tool for managing the NetworkManager application and reporting on the status of the network. It can be utilized as a substitution for nm-applet or other similar graphical clients. nmcli is used to display, create, delete, edit, activate, deactivate network connections, and control and display network device status.

If you have a Storm VPS or a Liquid Web Dedicated server-based account and you want to update or modify the reverse DNS of your IP addresses, you can do so easily using your Manage account.

Introduction

In this article, we will review the Nmap software program and multiple commands. Nmap is an open-source mainstream tool used by network administrators to scan ports and map networks. Nmap commands are primarily used to identify which ports certain software is running on our system. It is also used to discover available hosts and what services they are offering and detecting potential security risks. Using Nmap, you can check a single host or a complete network. In this tutorial, we will cover several basic as well as advanced Nmap commands in the “Pro Tips and Tricks” section of the article.
