I would like to know a few basic things about the IP addresses that begin with 192.168 tried to google about this, but couldn't find much.
Is this range of addresses used in all LANs and VPNs? Or is it used only when there are firewalls? Is the mask the same format (in the network of my company it is 255.255.255.0) in all LANs? The reason is that I would like to make a TCP/IP-based server for LANs that will only accept connections from the LAN computers, but want to generalize it to work in any LAN.
If someone could give me some hints or at least direct me to a source about the 192.168 range of IPs I would be very thankful.
