I'm working with 2 machines, one running Ubuntu 14.04 and the other running Windows 7. The IT team has assigned me several IP addresses (xxx.xx.79.20 to xxx.xx.79.24) and I am trying to set static IP for the 2 machines.
The Ubuntu machine works well with any IP in the list, but the Windows machine work with none of them (I'm sure the subnet mask, gateway and DNS are correct). What makes me more confusing is, I tried another address on the same subnet (xxx.xx.79.3) on the Windows machine and it works! One might explain this by saying the IP addresses in the list are all used by other users, but why my Ubuntu machine could use them?
A few more thing I noticed: when pinging from Ubuntu to the IP's in the list, the command has no output, while pinging to xxx.xx.89.3, ping outputs "host unreachable" for each packet sent.
