What is a subdomain?
A subdomain is an additional part of your main domain name. For example, members.coworkingspace.com or residents.coworkingspace.com are subdomains of the coworkingspace.com domain name. You can select a word for the subdomain to access your web app from your custom URL. Some common choices:
members
portal
community
residents
app
miembros
Set up a custom subdomain
Before setting up a custom subdomain in your application, you must complete the setup on your domain registrar's side.
In your domain registrar account
Log in to your domain registrar account.
Open the DNS control panel.
Create a new record with the following data:
Type | CNAME |
Name | your custom subdomain, for example |
Value |
|
TTL | leave the default value |
Double-check the correctness of the data. Instructions for common registrars:
In your web app
After the setup is complete on the side of your domain registrar, please follow the steps below to configure it in your web app:
The app owner needs to open Network Settings > General.
Enter your full custom subdomain into the "Custom Domain" field. For example,
members.coworkingspace.comorapp.coworkingspace.com.
Verify the setup
Once DNS records have been changed, they can take some to propagate, which means global DNS providers recognize they have been changed. Unlike nameserver changes, which can take up to 48 hours to propagate, the propagation of CNAME records is usually very quick.
A custom subdomain added to your web app will appear unverified until this process is complete and full propagation is achieved.
The owner of your app can check the propagation progress by clicking "Check the progress of propagation" under the "Custom Domain" field. The button redirects you to the DNS Checker website, where you can click "Search" and see if the propagation is complete.
