I am truly sorry for taking up everyone's time with my clearly embarrassing
message.

Clearly, it is impossible to have data move from point A to point Z over
private IP space, through multiple intervening networks, completely within
an overlay network on top of the existing internet without ever touching
the real internet address space.

It was silly of me to think that if I connected to dn42 in one part of the
planet from a server that happened to have several hundred TB of local
storage, and established the right peering sessions, I could transmit the
data from those disks to a different host halfway around the planet, also
connected to dn42 with the right peering sessions established, that wanted
to consume that data, all over the private IP overlay network, without ever
using public IP addresses.

I see now the folly of my thinking, and I now understand that data can only
pass across the internet if it is properly associated with public IP
addresses.

My insane concept of passing data from one host to another via an encrypted
overlay network using only RFC1918 addresses was clearly the result of
insufficient sleep from patching and upgrading too many PHP servers this
week.

Thank you for setting me straight.

I will stop wasting everyone's time with my clearly impossible scenarios.

Thank you again for your patience and understanding as I learn from the
collected wisdom here.

Matt
