in our company. We would like to have 2 different subnet masks. 192.168.2.0/24 and 192.168.3.0/24. Could it be possible for the both subnet to communicate in a network? Need help. Thanks.

For example: Lan 1: Ip range:192.168.2.x subnet:255.255.255.0

Lan 2: Ip range:192.168.3.x subnet:255.255.255.0

Could both lan communicate to each other?

Yes. Of course different subnets can communicate with each other. You just need at least one piece of hardware which is connected to both networks and which knows how to route traffic between them.

Usually this is done with a router, but if you do not have one available you could use a multihomed PC.

It might be useful to read up on this post on Server Fault Q&A to learn how IPv4 subnetting works. (especially the part "You can't get there from here").

However you already tagged your post , so you probably are aware that such a device exists. Which confused me since the question "Could both LANs communicate to each other?" and the answer (in the tag) are already next to each other. What was it precisely that you wanted to ask?

  • thank you sir for the reply. Yes we already have a router. What do i mean is, How does ip-range 192.168.2.0/24 and 192.168.3.0/24 be able to ping and communicate to each other? thanks a lot. – ronald123 Aug 17 '16 at 11:35

    Which kind of router do you have? Different brands use different commands. Some you ssh into, some have a web interface. Please look up the model and add that to your post. – Hennes Aug 17 '16 at 11:43
  • Our router is tp-link sir.. – ronald123 Aug 17 '16 at 12:33
  • tp-link is a manufacturer who mostly makes SoHO devices. Q: Do you have a 'router' (and is so, which specific model) or a thing many people call router which actually is not a router but a many-in-one devices with modem+firewall+wirelessAccessPoint+switch... ? – Hennes Aug 17 '16 at 12:40
