I am using the following update URLs in the Fritzbox UI (v7.21 FB7590):

https://ipv4.nsupdate.info/nic/update 
https://ipv6.nsupdate.info/nic/update?myip=<ip6lanprefix>

The IPv6 prefix that is sent by the FB updater leads to following error:
received bad ip address: '2a02:908:1200:1234::/64'

Looking at the code, it seems that check_ip() does not recognize this as an ip address.
