Thanks for the reply Mark! The "local ipv6 address" output line contains "autoconf" flag, so I believe this has been configured after reception of RA packet with prefix "fd92:7065:b8e:0"
inet6 fd92:7065:b8e:0:214:22ff:fed9:fbdc prefixlen 64 autoconf If this is the case, then I assume all the nodes in the site will have the same prefix (includes global id). So from the host point of view, this local ipv6 address will behave like yet another global address and doesn't need any implementation for generating random global id.
