Quoting Ruben Safir (ruben-at-mrbrklyn.com):
> How can I ping and not have the mac address?
Destination i.root-servers.net is non-local. ARP works only on your local LAN, i.e., at the level of the link layer and within the boundaries of a single network, and is not routed across internetwork nodes.
> The linked layer frame uses the destination > mac of the Masquaraded router?
Yes, that being the relevant gateway.
> I thought the arps would go upstream all the hops and deliver the mac?
You thought wrong.
