Hi

I have a VERY basic knowledge of networking, so please be patient :)

I currently have an IP address of 192.168.1.3 (subnet mask 255.255.255.0)
This is groovy and I can see everyone on my network within my range of 192.168.1.1 - 192.168.1.254

Ok, now I want to be able to see a machine on a different range (3rd octet is different) without having to change my ip do be on the same range.

can this be done with some clever subnet mask?
The ip I want to hit is 192.168.5.5 but i still want access to the machines on 192.168.1.x

thanks

then why does it have a different IP address? why isn't it on the 1.0 network?

can't because of software running on it.
The applications are configured with that IP and I cant get the supplier to change it in the short term.

just trying to find the easiest method here

what about changing the other computers to the 5.0 subnet?

what kind of router are you using? if you've got a more corporate type router you can apply a subinterface ip to the main LAN interface which would route traffic between the subnets

the biggest issue with using the subnet mask to get from the 1.0 to the 5.0 network is that you're also opening up the range for 2.0, 3.0, and 4.0 in the process...also you'd have to make that change in a lot of places for it to take effect...

How can a device with a .5.0 network address belong to a network of .1.0?
Just curious.
