[Nfd-dev] autoconfig connects me to spurs (UCLA) instead of aleph (REMAP)

[Junxiao Shi]

Hi Peter

Wireshark capture indicates that the router is found via NDN-FCH service. It is the router that is geographically closest to you, as determined by reverse geocode lookup of your IP address. NDN-FCH stage occurs before “home router” stage in which your certificate is considered.
Therefore, connecting to aleph is expected if your IP address is near that router.

One problem I notice is that the logging message does not adequately identify NDN-FCH is being used. I’ve entered Bug 4079 <https://redmine.named-data.net/issues/4079> for that.

Yours, Junxiao
