But that is all speculation/opinion/non-first hand knowledge, you can't actually say any of those things in court without an expert witness. Only expert witnesses can testify to things that they didn't witness themselves, lawyers and lay witnesses cannot.
Also don't think you can simply get the opposing expert witness to give this kind of testimony on cross examination. During cross examination you can only ask them about things they testified to during direct (and a few other things such as their qualifications). So if they never testified anything about your IP during direct then you can't ask them about whether or not your IP matched during cross.
If you don't have the money to pay for an expert witness then you better just hope that the jury already knows about IP addresses and actually realizes that IP addresses matching was never brought up during the trial (they won't btw, the general public knows nothing about these things).
Think about it this way, all this techno mumbo-jumbo about account IDs and IP addresses may as well be black magic as far as the jury and court is concerned. So only a verified expert witness can testify about them. If we allowed otherwise then every trial would be nothing but testimony about how various magical or religious principles mean that you can't possibly be guilty (or vice versa).
