[LEDE-DEV] DDNS for ipv6

[e9hack]

Hi,

ddns for ipv6 doesn't work since the last few updates related to the ddns package. From log file:

Mon Jan 15 17:35:21 2018 user.notice DEBUG: hotplug igmpproxy: device 'wan_6' action 'ifup'
Mon Jan 15 17:35:22 2018 user.notice ddns-scripts[7394]: dynv6_ipv6: PID '7394' started at 2018-01-15 17:35
Mon Jan 15 17:35:23 2018 user.err ddns-scripts[7394]: dynv6_ipv6: Can not detect local IP using network_get_ipaddr6
'wan_6' - Error: '1' - TERMINATE
Mon Jan 15 17:35:23 2018 user.warn ddns-scripts[7394]: dynv6_ipv6: PID '7394' exit WITH ERROR '1' at 2018-01-15 17:35

This is immediately after a sysupgrade. Restarting of the service brings it back.

Ddns provider is dynv6.com.
