If you have two networks with hamachi, how do you see the ip addresses of both networks?

Unfortunately, Ender, that isn't how LogMeIn Hamachi works. Your IP-v4 address is your Hamachi address. When people connect to your server, they're connecting using your Hamachi address. The groups are just groups of people who can connect to your Hamachi address. If you create another network, it's just a separate group of people who are allowed to connect to your single Hamachi IP-v4 address.

If you want to make another Minecraft server, I'm assuming you are using "Open to LAN". You can open up a separate client and on both clients, you can click "Open to LAN". You will receive 2 separate ports, and will have 2 servers up. For example, if your Hamachi IP-v4 is 127.0.0.1, to connect to the first server you would attach the port you got at the end of that, and the same for the second one. The two IPs for the separate servers might look something like this: "127.0.0.1:25565" "127.0.0.1:56552".
