How to test Azure Web App that requires custom domain without using public DNS - azure

I have an Azure Webapp on a Standard 1 Small App Service Plan, I deployed my application successfully to the webapp, but now I need to test it using a specific domain name that on client side could be configured using hosts file.
The problem is that the Azure webapp will only "recognize" the custom/specific domain (ex: myapp.mydomain.com) if I configure a Custom Domain that uses public DNS and I can't (at this moment) configure the existing domain name to be a CNAME to the Azure webapp because it is production environment, I can and will make the CNAME after the application is tested not before.
My application requires to be called by the specific domain name.
So how can I test my application on Azure webapp using a custom domain but without using public DNS using only my hosts file client side?
note: this problem doesn't even exist in AWS Beanstalk so why is this so complicated with Azure webapp. Its pretty basic

You can preemptively associate your custom domain name with your web app and test it via a client using the host file. To verify domain ownership, Add a TXT record. The TXT record maps from awverify.<subdomain> to <appname>.azurewebsites.net. Steps to do this are outlined here:
https://learn.microsoft.com/en-us/azure/app-service/manage-custom-dns-migrate-domain

Using App Service, I don't think you can do this.
It configures the underlying app to only listen for domains configured in the Web App.
So if you don't add the domain as a custom domain, requests won't be routed to the app.
The reason is that IP addresses are shared, so Azure relies on the Host header to route your request correctly.
You can add the custom domain without CNAME / A record by using the awverify record mentioned by Ken.

Change domain for Pull Request environments in Azure Static Web Apps

Is it possible to change the domain for which Pull Request environments are built to? Currently we have our main branch built to a custom domain https://dev.mycompany.com and PR environments are built to the generated domain https://icy-flower-07e440303-{Pull Request ID}.westeurope.azurestaticapps.net. I would like them to be something like https://{Pull Request ID}.dev.mycompany.com so that our CORS rules still applies.
you can apply a custom domain directly to the static app. To do this you need to make a dns entry in the azure dns or any other dns registry then configure the static app to use the custom domain.
Dns registry can be done just by going to the azure dns in the portal click on the + button and fill the required details
Then you can configure the static app by providing the custom domain in the setting under custom domain option.
Refer the following documentation.

How to have multiple host names for azure website

I created an web app for a demo website in Azure. The domain name for this website was created when I created the app service "myapp1.azurewebsites.net". I'd like to use additional domain names using the same azurewebsites.net such as myapp2.azurewebsites.net. When I try to add this custom domain it tells me
Failed to add hostname myapp2.azurewebsites.net. Too many (2)
hostnames in the default DNS zone. Limit is 1
Is there no way around this or must I use my own custom DNS name?
For this you need to add custom domain in Azure web app.
For example : when I created the app service "myapp1.azurewebsites.net" and want to have additional domain names , you can go for custom domains like abc.com.
You can not have .azurewebsites.net as the custom domain of already existing web app as it is already owned by Microsoft Azure web app.

Web app not validating custom domain name

Steps I followed:
Created an web app (registration-ceus.azurewebsites.net)
Created a traffic manager profile, added web app as an endpoint (registrationtmp.trafficmanager.net) Traffic manager opens the web
app. Issue I face while adding custom domain. I have own a domain
(e.g myworkdomain.net)
I am trying to add subdomain to traffic manager profile (testregistration.myworkdomain.net).
testregistration.myworkdomain.net CNAME
registrationtmp.trafficmanager.net
Added CNAME for my web app:
awverify.testregistration.myworkdomain.net CNAME
awverify.testregistration.registration-ceus.azurewebsites.net
When trying to add the Custom domain awverify.testregistration.myworkdomain.net to my web app, web app
does not validate the domain name. It always gives option to Add
Hostname.
When I try to access testregistration.myworkdomain.net, gets 404 error.
The app service is in Standard tier. What step am I missing or doing wrong?

Azure App Service - My Host file

I published my app on Azure App Service.
I don't want to buy domain for now.
I just want to use my local Host file to connect to my Azure App with the futur domain I will buy.
I added an entry in host file:
ip.ip.ip.ip mywebsite.com
But how could I configure my Azure App?
This will not work. Azure App Services work on the basis of DNS Names. By adding the above entry in the host file, the record will reach the App Services Front-End Servers. However, they will not be able to map the domain name to a web app and this will result in a 404 error.
You will have to map a domain name to your Azure Web App in order to get this working. This implies that you will need to own a domain name, this in turn implies that you need to buy a domain name. :-)
If you want to use an IP address, you can use a cloud service web worker role (probably with a reserved IP, if you don't want a dynamic IP) instead of an Azure web app.

Multiple domains on 1 cloud service

I have a app which is a website builder. Lets say the app is on a azure webrole and its domain is called www.myapp.com.
I want to offer a service where users can use their custom domain with my app. So User 1 has a domain called ww.user1.com, user2 has www.user2.com etc. Whenever someone types www.user1.com, I want them to be able to see come to my my app ie www.myapp.com, with the browser still showing www.user1.com. You can assume I have complete access to the DNS and nameservers of these custom domains. I just need to understand how to configure this in azure.
Not really, as it was on SSL binding of multiple custom domains on a single cloud. I was trying to figure out how to have one app on a cloud service where content changes as per custom domain end user has used to navigate to the website. Turns out its easy, all that is required is cname config and listening to host_header on server side aspx page_init –
