When I set ip6hostid for my LAN interface to 'eui64', LuCI will not show the correct/actual IPv6 addresses in the overview under "Network" -> "Interfaces". The addresses are still shown as " + ::1/64" (e.g.: 2a09:7657:fee0:12f0::1/64), while in fact the interface is correctly assigned an IPv6 address in the form of " + ". Over SSH I can verify that the command 'ip addr' will show the correct IPv6 address, but not any IPv6 address that ends in ::1. The output of 'ubus call network.interface.lan status' will also show the eui64-derived IPv6 address and not the default one ending in ::1.

Based on my findings described in FS#1234, I assume that the same issue will occur when ip6hostid is set to 'random', but I have not tested this.

I observed this on LEDE 17.01.4.
