Custom Domains and DNS Configuration for Cloudmersive Reverse Proxy Managed Instance
5/3/2022 - Cloudmersive Support


When using Cloudmersive Reverse Proxy in Managed Instance, you can configure a custom domain name for your Managed Instance, e.g. www.mydomain.com.

There are two approaches to achieving this:

CNAME Record

You can complete this by adding a CNAME DNS record to your DNS provider's records that points to the fully-qualified domain name (FQDN) of your Cloudmersive Managed Instance. This could look something like this:

CNAME www.mydomain.com to my-managed-instance.cloudmersive.io

This will allow users who go to www.mydomain.com to be directed to your Cloudmersive Managed Instance. With this approach, you will not need to know or hard code your Cloudmersive IP address. For this reason, this is the simplest and best approach for most customers. If the Cloudmersive domain has a DNS-level failover then this approach will automatically still send users to the right updated endpoint.

A Record

You can complete this by adding an A DNS record to your DNS provider's records that points to the static IP address of your Cloudmersive Managed Instance. This could look something like this:

A www.mydomain.com to 55.55.55.55

This will allow users who go to www.mydomain.com to be directed to your Cloudmersive Managed Instance. If your Cloudmersive static IP address were to change, e.g. in the event of Disaster Recovery, you would need to manually update this record to point to the latest IP address.

To get your Cloudmersive static IP address, you can perform this command from the command line:

nslookup my-managed-instance.cloudmersive.io

SSL Certificate

If you wish to use HTTPS encryption with a custom domain, then you will need to provide a public encryption certificate.
