It seems sketchy to me to even retain client MAC information, no? Genuine question.
Didn’t we go to a distinct unique identifier system for this very reason? Am I in the 1990s here or? We’re just handing out addresses to UEs and things seem to work fine. For me personally, I find the notation of v6 to be very unasthetic, so I tend to just conceal it from myself now. -LB Ms. Lady Benjamin PD Cannon of Glencoe, ASCE 6x7 Networks & 6x7 Telecom, LLC CEO b...@6by7.net "The only fully end-to-end encrypted global telecommunications company in the world.” ANNOUNCING: 6x7 GLOBAL MARITIME <https://alexmhoulton.wixsite.com/6x7networks> FCC License KJ6FJJ > On Mar 19, 2022, at 3:56 PM, Matt Hoppes <mattli...@rivervalleyinternet.net> > wrote: > > > > On 3/19/22 6:50 PM, Michael Thomas wrote: >> On 3/19/22 3:47 PM, Matt Hoppes wrote: >>> It has "features" which are at a minimum problematic and at a maximum show >>> stoppers for network operators. >>> >>> IPv6 seems like it was designed to be a private network communication >>> stack, and how an ISP would use and distribute it was a second though. >> What might those be?
