Update an "A record" form to change an IP address associated with a FQDN, or fully qualified domain name. This effectively changes the IP address associated with an Internet address name, which is commonly used as a URL in a web browser.
The FQDN is a line stored in a DNS zone file. Referred to as an "A record," the line contains an FQDN and the associated IP address to which it refers. When users attempt to go to a Web address, the FQDN, such as "google.com," is referenced with a DNS server to find the associated IP address in the A record, which tells the browser where to connect to get the webpage requested. Updating the A record effectively changes the IP people are instructed to go to when navigating to a particular Web address.
