What Is DNS?
DNS or Domain Name System is a protocol used to translate a name into an IP Address used by computers to communicate over the Internet. DNS is essentially the phonebook of the Internet.
Why Do You Need To Check Your DNS?
When you register a new domain name, it is essential that your domain host links your website name and IP address properly. An AI DNS checker tool will help you check if your IP address and website name has been linked correctly.

What is DNS propagation?
DNS propagation is the process of checking the current state of the DNS results globally. The process is conducted when changes made to DNS zones are not working in the expected manner. The time taken for the process can take a few minutes, or it can take somewhere between 48-72 hours, maybe longer.
Technically speaking, DNS does not really propagate, but it is the term that is used most commonly. In order to expedite future lookup requests, DNS requests are recursively passed and looked up from the locally used resolver to the authoritative name server on demand and then cached. This is why you must select the most commonly used DNS servers of large network providers placed all over the world while performing the DNS checks.
For websites that enjoy more traffic, the DNS results may be cached on different recursive DNS resolvers for people who are accessing the website from different parts of the world.

How Does DNS Work?
DNS works by converting a hostname (www.example.com) into a computer-friendly IP address (192.168.1.1). An IP address is given to each device on the Internet, and that address is necessary to find the appropriate Internet device - like a street address is used to find a particular home.
When a user wants to go to a website, their URL must be translated into a machine-friendly IP address. When a user enters a URL, it passes through 4 DNS server, each with a different functionality:

The recursor receives the user’s URL and sends it forward through the internet as a DNS query.
Root Nameserver
The root server is the first step in translating a DNS query into an IP address. It provides references for the address a user is looking for.
TLD nameserver
TLD nameserver uses the references provided by the root server and hosts the end URL(.com, .co.uk, etc.), while providing a more detailed reference for the DNS query that is sent.
Authoritative server
The authoritative server is responsible for using the references and the provided query to find the correct IP address and send it back to the initial user.
Top Frequently Asked Questions
You can check your DNS using an AI DNS checker. An AI DNS checker helps you ensure that your domain host has linked your IP address and domain name correctly.
Private DNS is essentially DNS sent over TLS or HTTPS. To configure a private DNS, you need access to a third-party DNS server which allows you to configure manually. All private DNS does is give you a little more privacy while you browse a certain website.
There are no downsides to private DNS except that you need to set it up. You can use it if you want.
A DNS works by matching the URL you have entered to its respective IP address. Here’s how it works.
- Step 1:
You enter a URL. Your computer will check the local cache to see if the website already exists. If it doesn’t, it will send a DNS query to the nearest DNS server(recursive server).
- Step 2:
The DNS query is sent to a recursive server. Most ISPs use the same DNS servers. Each recursive server has its own local cache. If the domain name matches a certain IP address, it will answer your DNS query, and your page will load.
- If it doesn’t, your request is sent to an authoritative server.
- Step 3:
Your DNS query will then circulate to all DNS servers that store records looking for a potential match. These servers are known as authoritative servers. When a record is found, your local recursive server will save the record in its local cache and send the record to your computer.
- Step 4:
Your computer will read the record and save the domain IP in its local cache.
Resolving a domain name is a step-by-step process through which a DNS query is resolved. Check our FAQ on ‘How does DNS work step by step?’ to find out how domain names are resolved.
