Azure Route tables - Can use a domain?

Question

Hello, I got a routing table where I include some IPs for users of my client to use, thing is i've found out a website that needs to be included has a rotating ip, with 50+ ips.

Is there a way for me to just introduce website domain / anything that is not the ip so I don't have to input all the IPs that I come across? I'm using azure route tables and it doesn't seem to be an option.

Hello Frasi, unfortunately, Azure Route Tables do not support routing based on domain names or URLs. They are designed to work with IP addresses and CIDR ranges only. This means that you would need to manually input all the IP addresses associated with the website, which can be cumbersome, especially if the IPs are dynamic or frequently changing. Here are some alternative approaches:

1. Azure Firewall - You can use Azure Firewall to create application rules that allow or deny traffic based on domain names. This way, you can manage access to the website without needing to specify individual IP addresses
2. Network Virtual Appliance - Deploying an NVA that supports domain-based routing can help you manage traffic based on domain names. NVAs often come with more advanced routing capabilities compared to Azure Route Tables
3. Azure Application Gateway - If your use case involves web traffic, you might consider using Azure Application Gateway, which can route traffic based on URL paths and host headers. This can help you manage traffic to the website more effectively
