With current Raspberry OS (Debian GNU/Linux 12, bookworm) you get ddclient v3.10.0. This could not determine the ipv6 address !
The latest v3.11.2 worked fine, see next.

Install ddclient on your own#

> sudo apt purge ddclient
> sudo apt install libjson-any-perl libdata-validate-ip-perl libio-socket-ssl-perl
> sudo apt install libtool        # this is missing at najigram.com and solves issues if autogen does not work
> wget https://github.com/ddclient/ddclient/archive/refs/tags/v3.11.2.zip
> unzip v3.11.2.zip
> cd ddclient-3.11.2
> sudo ./autogen
> sudo ./configure --prefix=/usr --sysconfdir=/etc/ddclient --localstatedir=/var
> sudo make
> sudo make VERBOSE=1 check
> sudo make install	
> sudp cp sample-etc_systemd.service /etc/systemd/system/ddclient.service

Configure#

sudo cp ./sample-etc_systemd.service /etc/systemd/system/ddclient.service

sudo vi /etc/ddclient/ddclient.conf

verbose=yes # for detailed logging
