IP2Azure

This command-line tool allows you to quickly check if a given IPv4 address is used by an Azure service.

It does so by loading the public list of Azure IPs (which is published at https://www.microsoft.com/en-us/download/details.aspx?id=56519) and getting all the services whose published subnets contain the given IP.

A copy of this file is stored in this repository, under the data directory.

For example, from the src directory:

❯  dotnet run --azureJson ../data/ServiceTags_Public_20240408.json --address 20.51.10.137 -q
20.51.10.137 AzureResourceManager, AzureResourceManager.WestUS2, AzureCloud.westus2, AzureCloud

If the tool finds no matching services, it will only echo back the given IP. Example:

❯  dotnet run --azureJson ../data/ServiceTags_Public_20240408.json --address 127.0.0.1 -q
127.0.0.1
