DNS Record Update Scenarios: When to Update DNS
After DNS is configured, there isn't much to do besides troubleshooting and updating as necessary. After initial setup, there are times when you must manage your DNS or Advanced DNS. See the DNS record update scenarios below.
Here are some situations where a DNS record change may be required:
- New Hosting Provider
- New Email Provider
- Point a Subdomain
- Add Additional Advanced DNS Records
- DNS Issues
- Review
New Hosting Provider
You must update your nameservers if your hosting provider changes. You can switch the hosting company in charge of your website and email address using nameservers.

New Email Provider
You must update your MX records if you switch your email service provider. MX records are necessary mail records used to set up a domain name's mail route. This means that if your email is not hosted by your hosting company or if you wish to add an extra mail route, you must create an MX record.

Point a Subdomain
You might need to add or modify NS records if you want to point a subdomain to another server. The nameservers for your subdomain are identified via NS records. You use this to control how records on your subdomain are handled.

Add Additional Advanced DNS Records
Over time, you may need additional DNS records for your products and services, such as adding an SPF record to let the servers of your email recipients know the sender is legitimate.
