Dns Lookup


Definition of DNS Lookup

DNS stands for Domain Name System and is a protocol that is used to match the domain names (e.g., google.com) with an IP address (e.g., The DNS lookup process helps the browser to find out how to connect to a web server in order to request data, by looking up which server it should communicate with during the HTTP handshake process.

A DNS lookup will return all of the records associated with a given domain name, so if you are looking up your own web site you might get back your MX record, A record, CNAME record, etc., but when you are looking up someone else's site you might not get anything back at all.

For example, if you type in google.com the search engine might return mail.google.com as a record that you can use to reach Google's SMTP server for email delivery which will send your message back to the originating source; however, my own domain name (automattic.com) has no records and hence Google is unable to contact me using these means.


What is DNS (Domain Name System)?

Domain Name System (DNS) is a system that converts domain names into IP addresses. It is an important part of the Internet infrastructure and allows users to access web sites by using domain names instead of difficult to remember numerical IP addresses.


How DNS Works?

The Domain Name System, or DNS, is an important technology in the digital world. It allows people to connect to websites without having to remember their IP address.

A domain name server is a type of server that translates human-readable domain names into computer-readable IP addresses. There are hundreds of thousands of these servers all over the world with the most popular being in the US, where many websites are hosted.


Benefits of using a DNS lookup service?

DNS lookup services are useful in networks. They map IP addresses to hostnames. The mapping is done with the help of a DNS server, which is usually located at your ISP's office or at an independent third-party location.

The DNS server stores the mapping data in an online database that can be queried by any computer connected to it.

Therefore, you can use a DNS lookup service instead of typing an IP address directly into browser address bar for example, to find the URL of the website you would like to visit.


What are the most common problems with DNS lookups?

DNS lookups are a process of translating a domain name, such as "facebook.com," to an IP address, such as "" The most common problems with DNS lookups include latency and timeouts, which can lead to a failed connection or slow loading speeds on a webpage.

Latency is the time it takes for data to travel from one computer to another over the Internet. This can be caused by many factors, including distance from your location to the server hosting the webpage and traffic on the Internet line connecting you to that server.

Timeouts occur when your device had been waiting for a server request for more than 10 seconds without receiving any response from the server, so it gives up and displays an error message instead of waiting any longer.


How to troubleshoot your DNS settings?

It is very important that we set up our DNS settings in order to get a good connection with the internet. However, sometimes, this process becomes more complicated and we might need to troubleshoot them.

One of the most common troubleshooting steps is checking the DNS server and IP address in your network connections. If they point to a different IP address or DNS server, you can change them by going to your IP configuration settings on your computer.

From there you can choose which DNS server you want to use by typing in its IP address and selecting it from the list. After this step is done, restart your computer.
