Yes, even though I can see the Canterbury University buildings from our back yard, the download has to take the long "slow" road via Auckland. Our location on every website comes up as Auckland. I assume this is a cheaper way for MR to operate?
Didn't know what CGNAT was so asked Dr. Google;
"CGNAT enables organizations to deliver transparent IPv4 connectivity and a seamless user experience while oversubscribing their limited global IPv4 addresses. Carriers can assign local (private) IPv4 addresses in their access network, and use a centralized device to manage the address translation to the global (public) Internet."
I assume this all means that when more subscribers come online in the evening, they all get squashed together through the MR system, and the result is that everything slows down?
Do the other ISP's, eg Spark, Vodafone, BigPipe, Orcon, Slingshot etc, not use CGNAT?
