I have a question regarding the IP address of my web application.
I deployed my app to azure. The application (API) has been successfully deployed to azure web service and for a client to make a request to the API, the IP address of the app is needed. In azure portal under properties I can find the virtual IP address (e.g. 20.10.200.5 typing it to the browser gives 404) and outbound API addresses.
How to make the API's virtual IP address reachable by clients ?
As an addition to Stanley's answer:
The App Service gets its own URL in the form of <appservice-name>.azurewebsites.net which can be used to access the application / API. You can also Map an existing custom DNS name to Azure App Service making the application / API available through your own domain, like yourdomain.com/api.
Unfortunately, you can't access an Azure App service directly by virtual IP. Virtual IP is bind to the App service plan, one App service plan could contain multiple Azure App services. App service plan maps the domain name with the individual app services, so using a virtual IP is not possible to do that.

Playing with Azure App Service, I instantiated a simple web app. I tried to identify its IP address and found one in the properties of my app. It was described as 'virtual IP address'.
Trying to ping it or put it in my browser, it doesn't work and I can't find if it's an Azure configuration or a principle of virtual IP addresses... To be more precise, if I type '40.79.130.128' in my search bar, I crash on a 404 page, instead of my website page.
I read a bit on the topic, mainly what it is used for, but I don't understand if I can just reach it in my browser, because just typing it in my search bar is no use. What am I missing?
The Virtual IP address under your App Service on the blade Settings->Properties is the Shared IP.
The way IP address work in App Service is different. App Service app runs in an App Service plan, and App Service plans are deployed into one of the deployment units in the Azure infrastructure which is internally called a webspace and each of the deployment unit is assigned up to five virtual IP addresses, which includes one public inbound IP address and four outbound IP addresses.
All App Service plans in the same deployment unit, and app instances that run in them, share the same set of virtual IP addresses which means many App Services is behind same IP address hence you need to configure Custom Domain on your App Service to get it to work.
For configuring Custom domain refer to this link:
https://learn.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain
Please refer to below articles for details:
Inbound and outbound IP addresses in Azure App Service
App Service networking features
I have azure app service which runs .net core web api. This api access several external API s to get data and those external services has to whitelist the outbound ip addresses of my app service.
Azure app service has several outbound ip addresses and it can be change when upgrade/downgrade app service or when make internal changes like changing app service plan or resource group.
Is there any solution in azure to setup this app service behind a forward proxy ?, so i can share the IP of the forward proxy to external parties.
I think the best way would be to add all App services under a virtual network and create a Virtual Network Gateway to all outbound connections.
This would potentially need below azure services to be created:
- Virtual network
- Subnet
- Virtual Network gateway
- Routing tables (to route traffic via Gateway)
A better way would be sharing a domain name rather than IP address. Here's how to configure it directly in the Azure Portal:
https://learn.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-custom-domain
You can also add an API Management in front of your web app and use it as API gateway and also apply policies on it.

I have web and api app deployed within ILB ASE fronted by Application Gateway.Would I be able to make the calls from my web app to api app without exposing api app externally? If so, how can I do that?
I configured application gateway to point to the front end web app. I created internet routable domain and added to custom domain in my web app. In my DNS, I pointed the custom domain to hostname of the application gateway and I am able to logon to my web app. But, I see my web app written in AngualarJS is making XMLHttpRequest to backend API URL and as the backend API URL can not be resolved from my desktop, it is failing.
My requirement is not to expose API app outside of the ILB ASE VNET. Any suggestions?
If you want the web app and API could communicate with each other in an ILB ASE, you need to deploy an internal DNS service. For example, you could deploy a custom DNS server on Azure VM in the same Azure VNet. You can specify DNS server IP addresses in the VNet settings. The VNet is your ASE subnet located.
Please note that restart ASE after DNS IP address is added to VNet if you add the DNS after you deploy ASE. You could refer to this and read more details about custom DNS in ASE. Let me know if this works.
I have an azure website that I can access by
myname.azurewebsites.net
In Azure dashboard, the IP is 104.214.237.135
When I try to access my website by IP I have a 404 error
I don't understand. My plan App Service is S1

Azure App Service is a multi-tenant service, except for App Service Environments. Apps that are not in an App Service environment (not in the Isolated tier) share network infrastructure with other apps. As a result, the inbound and outbound IP addresses of an app can be different, and can even change in certain situations.
App Service Environments use dedicated network infrastructures, so apps running in an App Service environment get static, dedicated IP addresses both for inbound and outbound connections.
Azure AppService IP addresses are shared between tenants and not guaranteed to be static. Your app is bound to the hostname, not the IP address. Unless you are using App Service Environment, you cannot use a static / dedicated IP address with Azure AppServices. You can add additional custom hostnames to your app.
I have created an Azure App Service Environment with 4 IP Addresses but all of them are unassigned. I have a bunch of app services and I need to have one IP per app service.
I figured it out. You need to upload a SSL certificate (you can buy it in Azure portal or from any other company), import it and bind it. When you bind it you say it's an IP Based SSL. After you save you get a dedicated IP for that app service.
