I am not sure that desktop printer will able to print up to edges of A4 sheet and there will be a tiny white frame around. 

If you will not like to crop this frame, you, obviously, don't need to do a bleeding.

Do we need bleed if the Print output isn't intended to be cut (as is output)
I have noticed a certain pattern in a wireless network. It goes something like this:


All mobile devices (Android and iOS) take the subnet 10.8.5.x.
All laptops (Windows and Linux) take the subnet 10.8.3.x.


It might be pure coincidence, but I like to believe there is something else going on. If such mechanism on the router (i.e. providing different ip subnets to different device types) exists, how is it called? And how is the router able to distinguish between the different device types, isn't the MAC address everything it gets from the device?

Thanks in advance.
