I can confirm this issue. The following configuration has been working fine with 3.9:
ssl=yes protocol=dyndns2 usev6=if, if=br0 server=<redacted> login=<redacted> password='<redacted>' XX.XXXXXX.de Running ddclient: WARNING: '' is not a valid IPv4 or IPv6 address WARNING: found neither IPv4 nor IPv6 address WARNING: XX.XXXXXX.de: unable to determine IP address with strategy use=ip WARNING: 'usev6=if' is deprecated. Use 'usev6=ifv6' Use of uninitialized value $ip in string at /usr/bin/ddclient line 3639. Use of uninitialized value $_[2] in sprintf at /usr/bin/ddclient line 2160.For some reason it tries to use strategy "use=ip", when usev6=if is requested.
