I'm trying to create a message program that works without a server, but I'm looking for information that I can use as a reference.

I have a question because there is only client <-> server information on Google. I'm trying to create a message program that works without a server, but I don't know how to do it I'm not getting my bearings. The most ideal reference programs are x-popup and MsgPopupII It's a message program, and it's about finding users who are installed in the same program and going back without a server I'm most curious.

python socket

In the case of MsgPopupII, I opened the website and found this saying.

HW requirements LAN card : TCP/IP protocol installed, dynamic IP is not available. If it is dynamic IP, set it to static IP on the DHCP server
Source: First screen

Q: Which port number does message pop-up use for TCP/IP?
A : TCP port : 6713 6715
UDP 6711(A group) ~ 6716(F group)
Source: FAQ

In short, internal TCP/IP communication. I haven't looked it up, but maybe x-popup works on the same principle. I think you should look into the field of TCP/IP socket communication.
