Opinions / Discussion on copy protection / Software licensing through phoning home

Question

I am developing some software that I am going to end up selling. I thought about different copy protection mechanisms, both user and third-party. I know that copy protection is not 100% full of evidence, but I need to at least try. So I'm looking for some opinions on my approach, which I think of:

One of the ways that I think of is to simply connect my software to a remote server when it starts, to check the license based on the MAC address of the Ethernet port.

• I'm not sure if the server will work with a MySQL database that retrieves license information, or what ... Is there an easier way? Maybe some kind of encrypted file that is being read?
• I would make the software still work if it cannot connect to the server. I do not want to block someone because they do not have access to the Internet at that moment. In case you are interested, the software that I develop is extremely dependent on the Internet / network. Thus, it is actually unlikely that the user will not have access to the Internet when using it. In fact, it is pretty useless without internet / network access.
• Does anyone know what I will do with computers with multiple MAC addresses? Many motherboards these days have 2 Ethernet ports. And most laptops have 1 Ethernet port, 1 Wi-Fi and Bluetooth MAC addresses. I suppose I could just select the MAC port and start it. Not sure if that really matters.
