DNS records: How to change your DNS records

Changing your DNS records

In some situations your web developer will ask you to change your DNS records so that your web site operates from another platform. They will provide you with an IP address and ask that you update your DNS records.

The following guide will show you how to change your A record, so that your web site points to another platform whilst leaving your email to continue operating within your FASTDOT account.

Changing your MX Record Record

What are DNS records

DNS (Domain Name System) records are essentially a database of information that maps domain names to IP addresses. When a user types a domain name (such as example.com) into their web browser, the DNS system translates that domain name into an IP address (such as that the browser can use to locate the website. DNS records include different types of data, such as:

1. A (address) records: maps a domain name to an IPv4 address.

2. AAAA (address) records: maps a domain name to an IPv6 address.

3. MX (mail exchange) records: specifies the mail server responsible for handling email messages for a domain name.

4. CNAME (canonical name) records: maps an alias name (such as www) to the canonical domain name (such as example.com).

5. TXT (text) records: provides additional information about a domain name, such as the domain owner or authentication information.

DNS records are managed by domain name registrars or DNS hosting providers, and they can be updated or modified as needed. They are critical to the functioning of the internet, as they allow users to easily locate websites and other online resources using domain names rather than numeric IP addresses.
