A complete Guide To DNS Records Lookup

How to Perform a DNS Lookup When you’re planning to launch your new website. It is important to ensure that your domain name has been correctly registered with the appropriate domain registrar (GoDaddy, Namecheap, etc.).

Once you’ve purchased the domain name, you will need to configure your hosting server so that it can process DNS queries and lookups correctly on your behalf. This article will walk you through how to perform a DNS lookup using the DNS lookup command-line tool on Windows and Linux operating systems.

SEO and internet marketing professionals often need to perform DNS lookups when testing email deliverability, website development, and more. The process can be confusing at first, so we’ve created this ultimate guide on how to perform a DNS lookup to help you understand exactly what’s going on behind the scenes when your computer requests information from one of the internet’s biggest databases.

First Things First

The DNS (Domain Name System) is one of those essential, but invisible, pieces of the Internet infrastructure that we all use every day. In its most basic form, it’s how you type a website into your browser and have it bring up what you’re looking for.

However, there’s quite a bit more to it than that – once you understand some of DNS’ quirks and behavior patterns. This can be extremely helpful when debugging or just trying to make sense of why your site isn’t performing as well as it should be.

Why Is the Hostname Important?

If you have ever wondered why domain names must always be hosted on DNS servers then you’re definitely not alone. In fact, we would go as far as saying that at least 95% of all people. Whoever worked with domains on a professional level has asked themselves that question at one point or another. If that’s the case, why is it so crucial?

After all, doesn’t it just need to connect IP addresses with hostnames and vice versa? Actually, things are much more complicated than they appear! The truth is most of us don’t even know how DNS lookup works and what exactly we look for when doing it. 

To shed some light on these questions, let’s take a closer look at DNS lookup from both theoretical and practical perspectives.

So, what exactly is DNS lookup and how does it work? We are glad you asked! The easiest way to explain that would be just by using an example. Imagine that you want to contact another person but forgot his phone number.

What do you do? You probably call someone who knows him and asks for it, right? Well, in a similar manner, your computer asks another DNS server (let’s call it A) for information about the domain address when you enter a specific domain name into your browser’s address bar.

The thing is not all servers that answer your query will provide accurate results so your computer will repeat these requests multiple times until it gets all of them from different servers which in theory should provide correct responses.

Validating Your IP Address

You’ve purchased your domain, set up hosting for it on an Internet Service Provider (ISP), and now you’re ready to create your website. If you want visitors from around the world to be able to access your site quickly and easily, then you need a Domain Name System (DNS) lookup.

DNS lookups are used by ISPs, web browsers, and internet routers all over the world; without them, websites would be virtually impossible to visit from overseas.

You can do some basic troubleshooting of your DNS setup yourself using online tools or third-party programs like CanYouSeeMe?, but most webmasters will probably find it easier just to ask their ISP what they should use as their primary and secondary name servers.

Name Servers Lookup- What Are They?

A name server is a software that points visitors to your website or files (or hosts them. Which is why you’re probably looking up DNS lookup) to different IP addresses depending on who they are. For example, your website’s visitors will be directed through their name servers over to your web server. Where they’ll be greeted with whatever files they want to be displayed on your site.

In other words, it serves as an Internet address book for anyone who needs access to your online content. You can create and edit custom DNS records at any time in most web hosting control panels. Or simply ask your provider for help if you have trouble doing so yourself.

How Do I Find My Name Servers?

Domain Name System (DNS) is one of those aspects of network management that everyone should understand, but few do. DNS isn’t just for system administrators and webmasters. Whether you work in an office or manage your home network. It’s important to know how to perform a DNS lookup. Here’s a rundown of how it works and why it’s important. 

How Do I Find My DNS Servers?: Go to Start > Run and type CMD into the box. This will show you what DNS servers are set up on your computer Click OK. This will open up a command prompt window where you can type commands. Type ipconfig /all at the prompt (no quotes).

Look for IPv4 Address next to DNS Servers: entry under Ethernet adapter Local Area Connection X where X is some number between 1 and 4 depending on how many adapters you have installed on your computer.

These are usually two entries labeled as such; one entry will be active while another entry will be inactive with Reserved beside it. Make sure you note which entry is active because that’s what you’ll need to configure later if necessary.

Understanding MX Records

In order to move mail between different mail servers, domain name servers and MX records (MXR) are necessary. These records, sometimes referred to as mail exchangers, allow for email routing. When you are configuring MX records for your domain(s).

It is important that you choose an e-mail service provider with more than one server in case one goes down. If an MX record contains only one IP address, it will go down and so will your business’ e-mail services. As such, it is best practice to configure multiple IP addresses for your MX record. Both from within and outside of your network.

How To Create An Alias Record In DNS?

An alias record, also known as an A record, is used to define an entry for a particular address in DNS. The hostname (or fully qualified domain name, or FQDN) becomes associated with another hostname and/or IP address.

This process is commonly referred to as mapping or resolving. The address can then be referenced by other computers on your network or across networks for website delivery purposes.

A Complete List of All DNS Records

Internet Protocol version 4 (IPv4) defines three types of addresses: unicast, broadcast, and multicast. Most of us are familiar with unicast IP addresses. A Dynamic Host Configuration Protocol (DHCP) server gives these to devices or networks. So they can talk to each other on the internetwork.

What about multicast and broadcast addresses? They serve different purposes, but each has specific characteristics that make them interesting in their own right. This guide will help you understand what you need to know about both types of address formats.

Six Types Of DNS Records

Six types of DNS records: There are six types of DNS records, although some of them may not be visible to you depending on how your registrar or DNS server is configured. They include A Records, CNAME (Canonical Name) Records, MX (Mail eXchange) Records, NS (Name Server) records, PTR (Pointer) Records, and SOA (Start of Authority) Records.

It’s important that you’re aware of all six. Because each one plays an important role in ensuring your website functions smoothly. As well as these five main records there is also another called TXT. Which stands for Text Record but isn’t used as often as it once was now that we have SPF records.

Traffic back from one domain name to another using CNAME records. For example, when you first sign up for web hosting. you’ll get an A record that points your site to the IP address of your server. If you decide that it’s easier or more practical for people to find and remember an alias domain.

Then it is an IP address, you can have a CNAME record set up that points. That alias domain name is at your original address (the A record). You should note that CNAME records only work in one direction. You can only set them up for domains in your zone file, not for domains outside of it.

Frequently Asked Questions:

What is the C Record in DNS?

A c-record, or Canonical Name record, is an object in DNS (Domain Name System) that points your domain or subdomain’s name servers (NSs) to your host names. The NS records are managed by you with your domain provider while c-records are managed on your server.

How to create Cname Record in DNS?

Using DNS, you can create different types of records that each have their own uses. One of these records is called a CNAME (canonical name) record, which is used to direct traffic from one domain or subdomain to another. Although they’re referred to as records, these entries actually appear within an existing DNS zone and function like any other record in that zone.
