Can devices with different subnet masks communicate?

If two computers are on different networks, they have a different subnet mask and they can’t communicate to each other, unless connected by a router.

How do I configure my router with a different subnet?

To connect to another router, please follow the steps below:

  1. Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable.
  2. Click on Advanced and then click Advanced Network. Uncheck the Enable UPnP checkbox.
  3. Click Setup and then click Network Settings.

Why do we use different subnet masks?

A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs. To better understand how IP addresses and subnet masks work, look at an IP address and see how it’s organized.

How can I tell if two devices are on the same subnet?

The most common subnet you will see is 255.255. 255.0. So if two addresses match in the first three sections (reading left to right), and the subnet is 255.255. 255.0 for both addresses, they are in the same subnet.

Can subnet mask be different?

Subnets can have different masks, it’s called VLSM (see Classless Inter-Domain Routing ). In your example you specified host addresses, not networks, since the host part of the IP addresses is not zero, and obviously /192 was meant to be /26. If we round the IP addresses to networks we get 192.168. 0.0/30, 192.168.

Can two different subnets communicate?

The short answer is that they can, but they need a router or layer 3 switch configured with the appropriate static routes to each network, or a dynamic routing protocol that learns the path from one subnet to another.

How do I connect to a different subnet?

How to Connect Computers That Are on 2 Different Subnets

  1. Connect the computers to the network.
  2. Connect the routers to each other.
  3. Enable a routing protocol in each subnet’s router.
  4. Allow time for the routing tables to update.

How do I isolate two networks?

To isolate one network from another, we need to separate them at two levels:

  1. The network layer (3 and 4 in the OSI model, or TCP/IP in the real world). This would mean separate netmasks and address ranges.
  2. The data link layer (2 in the OSI model, or Ethernet in the real world).
