[AusNOG] Telstra using US DOD IP's like they are RFC1918

[Paul Wilkins]

Second this. CGNAT space 100.64.0.0/10 is not for intercarrier
connectivity. It's specifically carrier <> internet. Otherwise, when your
administrative control changes (eg. they sell the company), you enter a
world of pain with separate ADs accessing the same space.

Kind regards

Paul Wilkins
