You can't. Even if you had a list of IP addresses and corresponding MACs you can't.
Probably the only thing you can do is, if they are public IP addresses, and you have good knowledge of all the carriers networks, is take a best guess based on the known 3G/4G ranges of each ISP.
For example, if I see a 220.127.116.11/8 IP address (which my phone often gets), chances are it's a smartphone on the Optus network.
But without that inside knowledge, you can't even begin to take a guess.
