Is the Azure App Service IP address a static IP address for DNS purposes?

Question

I can’t find out if the IP address that Azure App Services gives you is added to your DNS. The record for user domains is a really fixed IP address.

As far as I can tell, you cannot use reserved IP for application services.

According to the official documentation and some comments, the IP address we get is the virtual IP address. Does this mean that we may need to change the DNS DNS record in the future to a different IP address, even if we never change the application service? If so, when can this happen?

Answer 1

with the page you linked to

Note:
The IP address may change if you delete and recreate the web application or change the mode of the web application to free.

This means that until you are at a free level, you will receive a static IP address that you will save if you do not go to the free level or delete your application. - which was previously on the Portal, but I can not find it at the moment! - All my deployment scenarios simply ping the * .azurewebsites.net address and then add this to the DNS

Answer 2

App Service Environment (ASE) is a dedicated environment that provides such capabilities ( link for ASE ). This was also suggested in UserVoice - and the answer was to use ASE if you need a static IP address.

I think this is the only way to achieve what you need. Another way could be to look at outgoing IP addresses in the resource manager for your WebApp, but this is a pool that is not applicable.

Answer 3

if you want to be sure that your IP address will never change, you can configure a cloud service instance with a reserved IP address; this way, you don’t have to worry about changing IP addresses.
