your Ipv4 Address is: 18.119.128.75
your Ipv6 Address not detected

You can use a third party API, such as Ipify, to get the IP address of the current request in Blazor. The script api.ipify will return the IP address in JSON format. But this is a workaround. As of now, there is no way to achieve this. In the following code snippet, the IP address will be retrieved from the Ipify API through a JS interop call to the Blazor server.
