Hello colleagues I am using Sockets regardless of the programming language, I have 2 applications (Red Lan), one on the PC and another on a Notebook. I would like to know if it is necessary to have the OPEN PORT for the connection of the 2 applications in a LAN NETWORK? What address do I need to occupy so that the applications connect?
Could you help me xfa: /
What you have to validate is that the local windows firewall in the PCs allow the connection, it is not a topic of the local network since this will not prevent communication, but the local fiewwall of the PC

really you should only enable this on the pc that will expose the port to listen to the communication, or the part that acts as a server.
The ips you will use are from LAN, although I see that you implement IPv6, so you must validate that the socket supports it.
