This is a bonus question in my Networks class: I have to find a destination for which the path MTU < 1500 bytes.
For example using the command
traceroute -F www.uwaterloo.ca 1500 works, and
traceroute -F www.uwaterloo.ca 1501 doesnt.
So I need to find a destination that will fail under 1500 (and no it can not be a private network, that would be cheating).
I am suspecting this is a trick because nearly all IP over Ethernet implementations use the Ethernet V2 frame format, which supports 1500 MTU.
