BCI w/dynamic IPs, using a Zoom 5341J into a router PC running Arch Linux.
I think i have successfully pulled a /60; but am curious. It appears my router is still assigning a /64 prefix to the internal interface & advertising this prefix to LAN clients; however, in my DHCPv6 client log I see a reference to the router updating a prefix to /60.
Here is some logs from the wide dhcpv6 client ("external" is the name of the modem-side interface):

and here is the address that gets configured on the internal interface:
inet 172.16.16.1 netmask 255.255.0.0 broadcast 172.16.255.255inet6 2601:5:1480:801:aaaa:bbbb:cccc:dddd prefixlen 64 scopeid 0x0<global>inet6 fe80::a236:9fff:fe14:1ed prefixlen 64 scopeid 0x20<link>
is this to be expected? that with a /60, the router should advertise a /64 prefix address pool to LAN clients, with the 4th group incremented by 1?
