And NAT is required for networks that are behind too few IPv4 IP's.
With IPv6, users can put their devices out on the wild-west open internet without needing any kind of NAT or firewall for protection.
The large number of open access points in the wild points out the danger here -- most consumers know nothing about network security and will set up their home network with dozens of IoT devices all on the public internet behind their ISP's non-firewalling router because they can, and everything works.
- mmagin 9y agoIt is unlikely that ISPs are going to provide CPE that doesn't firewall incoming connections by default, even if it issues devices on the LAN real public IPv6 addresses.
- Johnny555 9y agoAbout as unlikely as ISP's providing Wifi routers that default to open with no WPA password as used to be common? They'll do whatever makes support easiest until they are forced to do otherwise by regulation or bad press.
- mmagin 9y agoThe first (2010-vintage Apple Airport Extreme) and second (2017-vintage TP-Link something something) I'd done IPv6 with behaved this way by default if you enabled IPv6. I don't see why Comcast or AT&T would likely do worse. Sure they could, but this is not the likely scenario.
- Johnny555 9y agoThen I imagine you don't have much experience with Comcast or AT&T if you don't see why they'd do worse than Apple.
