Subnet mask needs to be the same for all the machines on the network.
Typically on a home network, the subnet mask will be
(known as a /24 or 24 bit network), and this will provide enough scope
for 254 hosts on your network (including your router). The subnet mask
you've specified would give you 65534 hosts - many many more hosts
than a home network would ever need, and to be honest, more hosts than
most corporate networks need!
