An internal network of 10.10.10/24; okay.

And you're able to ping yourself, which is good -- just remember that
pinging yourself actually uses the loopback interface, not the network
interface, and has nothing to do with your network driver.

When attempting to ping a locally connected IP address and an ICMP host
unreachable message such as this one is generated, with a source address
of your local address, it generally indicates that you aren't able to arp
for the destination address. What does "arp -an" say for the 10.10.10.50
address -- "incomplete", or does it return a valid MAC address?

Nope, it's perfectly valid. Both 10.10.10.50 and 10.10.10.211 are in the
same subnet 10.10.10/24. The 10.10.10.211 address should be reachable
from 10.10.10.50 even with no default route.
