Question about Computers & Internet
all computers on the same physical subnet need to have ip addresses in common
meaning the first three numbers in aaa.bbb.ccc.ddd are the same and are different only in the ddd portion.
In addition, the subnet mask must be alike or ensure that some ip addresses are not excluded
Typical subnet mask is 255.255.255.0 or sometime 255.255.254.0
Usually, there's a gatway address; a target which is used to send packets out
of this machine and hopefully towards the other machine.
For all machines, use the Run->cmd and enteripconfig /allYou should have similar results on all machines, so look for major differences eg: gateway on one is 0.0.0.0 or not shown while other have non-zeros,
or ip address on one start 169.254 another starts with 192.168
The 169.254.y.z addresses are pecuilar
