Recently we observed that the IPs have enlarged in MS docs and will continue to do so in future. To come around with a feasible solution and not contact FIREWALL team everytime when there is new IP inclusionin MS docs IP Whitelisting we plan to implement APIM for static IP.
But the logic app we have has a trigger when a file arrives on SFTP location we wonder how to achive this via APIM. Please suggest a solution.
The link explains the IP change but we are looking for a solution to come around this.

By Adding Virtual Public IP of your API management to your logic ap IP specific ranges, that way you can secure your logic app.

I am very new to Cloudflare. So please bear with me. I need to access my website (hosted in Microsoft Azure - App Services) via IP address instead of the domain name.
To do this, I need to add HOST=www.mydomain.com into the HTTP header when requesting the website via IP address.
I heard it can be solved via Cloudflare, but the person I asked will not elaborate further. Is it possible? If yes, what service should I purchase? Any manual or instruction will be appreciated.
If Cloudflare isn't possible, do you have any service recommendations?
Thanks :)
The reason the host header is needed is because Azure App Services are multi-tenant (multiple apps on a single IP) by default. So, the server needs some way to know where to route your request to (the host name). In addition, IPs are not guaranteed to be static (they can change as you scale for instance).
It should be possible to secure a single static IP address using the following method -
https://learn.microsoft.com/en-us/azure/app-service/overview-inbound-outbound-ips#get-a-static-inbound-ip
What is unclear is whether or not this IP would also be dedicated (meaning only your domain would use it). This is what would be required in order to allow you to access the app service without a hostname specified.
Cloudflare will not solve this issue, as it sits at the DNS layer (domain name access). Accessing a server via IP would bypass Cloudflare entirely.
I have one azure function which call clients api.
Client want a azure function ip address to whitelist them in there api network so that my azure function can access there api.
I tried to give them all Outbound Ip Address I can get from azure function properties but i can see everytime im getting all new ip address.
How to get all possible ip address which i can give client to whitelist pls advice.
For production im using App Service Plan (S1: 1)
You can do this. There are different possibilities depending on the pricing tier. From not possible at all, to possible but may change, to possible and guaranteed that IP address will not change.
The bad news is that, possible and guaranteed that IP address will not change, requires using the isolated tier.
See: https://learn.microsoft.com/en-us/azure/azure-functions/ip-addresses#dedicated-ip-addresses
I suggest you look into using service tags: https://learn.microsoft.com/en-us/azure/virtual-network/service-tags-overview#available-service-tags

I am more a C# dev than a network admin and I am not understanding what happened.
I have a website hosted on an Azure Web App and I started to get a lot of repetitive requests from IP address 172.16.5.1, to a point that it affected the web server stability
The only way I found to fix the problem is to block this IP address, but I still have questions.
1) Is blocking the IP the best solution to the problem?
2) After googling, I found that this IP address is in the range of Private IP addresses. How can a private address reach my public web server?
3) Could it be another resource from my Azure subscription that could be making these requests?...I only have a web app configured so I don't know where these requests could come from internally
4) Can this be a DDoS attack?
This IP Address is private range as you found it, but needs more information to answer your couriosity.
I could say that’s not the best solution, you need to find out which resources on your Azure that use that IP and see why it sends a request to Web App.
This is possible when your Web App connected to the Virtual Network, discuss with your Network Admin or System Architect.
I’m quiet sure that your Web App is connected to Virtual Network or could be another instance of your Web App requesting each other.
I’m not quiet sure that was an external DDoS attack.
That appears to be the default gateway for a subnet. Check the Networking blade to see if you are integrated with a VNet. I would expect that probes from something in the VNet (AppGW, Azure Firewall, NVA, etc.) would come from the instance IP of that resource and not the default gateway, but you really need to see the subnet range and know what's in there. If this is a WebApp that is integrated with a VNet via point-to-site VPN, then maybe this is something from the VNet Gateway, like Keep Alives. That might be apparent in a network trace. Blocking that IP could result in some other service marking the WebApp as unhealthy and not routing traffic to it.
Lots of conjecture here, but like Rudy said, you're not getting an external DDOS attack from a private IP.
I have an Azure Scheduler Job which calls a REST endpoint over https.
The REST API is locked down by IP address so it's currently (and understandably) failing. So I need to add the Scheduler Job IP address to the API firewall.
The problem I have is I can't seem to find the IP address anywhere in the Azure Scheduler web interface.
Am I missing something or is it not possible to get the IP address in same way you can for other Azure resources (web apps, worker roles etc)?
Unfortunately Azure Scheduler does not reserve static IP, so the IP will change from deployment to deployment as we ship new changes. You may consider Logic Apps, which also supports calling REST endpoint over HTTPs, and does have static IP. See this link for more details: https://learn.microsoft.com/en-us/azure/app-service-logic/app-service-logic-limits-and-config?toc=%2fazure%2flogic-apps%2ftoc.json#configuration
Very late to the show but incase anyone else stumbles across this again, the IP addresses from the Azure Resource Explorer should get you what you need. See here for details on getting the IPs. You can also add the IPs for the relevant Azure Data Centers to your allow list if necessary.
I have a WebJob on an Azure Website that needs to connect to a VM Endpoint to make REST calls.
My Endpoint is configured to deny all except my company's IP range. Now what rule would I need to add or url should I use so my webjob can connect to the endpoint?
I have tried the following without success:
Allow my website virtual IP address in the ACL
Connect to the endpoint using the internal IP instead of the DNS without changing
the ACL
Connect to the endpoint using the public virtual IP instead
of the DNS without changing the ACL
This works but is not what I am looking for:
Remove the current ACL and allow all
Keep the ACL but add a /16 rule with my website IP
Thank you for your help, and let me know if you need precision!
I need the same thing but it seems as though is not possible right now. Looking at this answer on a related question:
Azure Web Sites do not have dedicated outbound IP addresses for each
deployment. This precludes you from using ACLs or Virtual Networks to
connect to your Redis / Solr virtual machines.
So even though you can have a (reasonably) fixed incoming IP address on Azure Websites, the outgoing address is highly unpredictable and as far as I can see, the only exclusion that you could make was to restrict it to the entire range of IP addresses for that data centre which is far from ideal.
A solution moving forward will be to connect your Azure Website and the VM on the same Virtual Network. As of my writing this it is still in Preview so it still is not ready for production use just yet.
