As explained here, with UDP, you don't "open" a connection to an address/port, you simply send data to an address/port. In Erlang this is done using :gen_udp.send/4 which accepts a socket, address, port, and data.

If I start python udplisten.py in one shell and run the following from another:

I don't think there is any way for a Function to know if an Alias has been used, but the point is it shouldn't matter. Inside the function you should always refer to the parameter as if its used by it's primary name.

If you need the parameter to act different depending on whether it's used an Alias that is not what an Alias is for and you should instead use different parameters, or a second parameter that acts as a switch.

By the way, if you're doing this because you want to use multiple parameters as ValueFromPipelineByPropertyName, you already can with individual parameters and you don't need to use Aliases to achieve this.

Accepting value from the pipeline by Value does need to be unique, for each different input type (e.g only one string can be by value, one int by value etc.). But accepting pipeline by Name can be enabled for every parameter (because each parameter name is unique).
