What are the rules to make 2 devices communicate using IP address?
Each device on an IP network requires 3 different pieces of information in order to correctly communicate with other devices on the network: an IP address, a subnet mask, and a broadcast address. You will usually see each of these numbers written as four “octets” (e.g. 198.41. 12.151, 255.255. 255.0, and 198.41.
An IP address conflict occurs when two or more devices on the same network are assigned the same IP address. Because of this setup, no two devices can have the same IP address on one network. If this happens, the network becomes confused by the duplicate IP addresses and can’t use them correctly.
How can I tell if two devices are connected to my network?
When comparing two IP address/subnet combinations, the addresses must match for any section where the subnet value is 255. For a subnet of 255.255. 255.0, we expect to see the first three sections of the IP address match (reading left to right) if they are in the same subnet.
How to connect between devices via switch and giving IP address for?
We can use the Cross-Over cable from connection icon, to connect each desktop to the switch. Click on Cross-Over cable, then click on desktop (PC0), after that click on the switch. Do this step with all desktops. Give an IP address for each desktops.
How does a device talk to a switch?
Devices (e.g. computers, laptops, etc.) are connected to the switch. Say there is device A connected to the switch and it wants to talk to device B (also connected to the switch). I understand that a switch allows the two devices to communicate without involving the router, but that is via MAC addresses (data-link layer).
What kind of address does a switch use?
The switch only knows MAC addresses, not IP addresses. This is a simplified version of what happens: The switch (assuming not a layer-3 switch) only involves itself with MAC addresses. This is where ARP comes into play.
Is it possible to connect two switches with different IP ranges?
Yes. If you don’t have a router all your devices must have ip-addresses in the same subnet for them to be able to reach each other over TCP/IP. (The switches themselves must also be connected, obviously.) I’m trying to be able to ping all the devices no matter which switch they are connected to. is it possible?
