Whats my DNS is an online tool that helps website owners and web admins verify their DNS Records domain by simply inputting their domain name. This tool translates your domain name into an IP Address, which helps the browser to communicate with the server to load the website's resources.
Whenever a new domain is registered, the hosting provider asks the website owner to set up DNS records to route traffic to the server. The website owner enters DNS records into the DNS database using an online panel provided by the domain registrar. When DNS records are set correctly; further, the site owner needs to verify the records by checking DNS A Record using the WhatsmyDNS tool. This tool instantly shows the newly entered DNS information by querying DNS records through various DNS servers worldwide. This process helps to check in which locations the DNS records are propagated. It is essential to check the propagation because DNS records need at least 24 to 48 hours to propagate globally fully.
The WhatsmyDNS tool is also essential for webmasters who have recently updated the existing DNS records of their old domain names. It is important to check for updated records globally to ensure that your users are viewing old or new versions of DNS records that affect routing towards the new website.
