Correct.  That info isn't in the packet.

No.

As I said above, the netmask isn't recorded in the packet, so no it's
not necessary to set the netmask in tcpreplay.  If you want a Layer 3
device (generally we think of a "switch" as Layer 2) to forward a
packet, then all that is necessary is that the source/dest IP's belong
to the appropriate networks (which is a function of the netmask).

Honestly, based on your questions, I'd highly recommend going to your
local library or used book store and picking up a copy of TCP/IP
Illustrated Vol 1 and reading up on networking.

Good luck!
