SRV Record

Hi,

First i'll start by saying I don't have any personal experience with python, other then compiling/running it,
I want to create a SRV record for stratum, But it seems like certain libraries or code needs to be added/changed in the server application ?

I know its a bit ancient, But here is a reference;

Does stratum already have a SRV record? Have i missed something?

Any assistance would be appreciated.
