This is the LINUX console which produced the Wireshark trace.
This was performed right after rebooting the machine.
In LINUX (as in Windows), the -n parameter on the "arp" command means to show only IP addresses, not DNS names.
Lines with a "#" sign in them have comments after the # sign. This is a LINUX (and UNIX) convention.
ifconfig # Shows the computer I am running on and the netmask
