Public bug reported:

Description: Ubuntu Xenial Xerus (development branch)
Release: 16.04
ifupdown:
Installed: 0.8.10ubuntu1
Candidate: 0.8.10ubuntu1
=
For the inet6 static method, interfaces(5) implies that only 'address'
is required (and thus netmask is optional), however settle-dad.sh
assumes IF_NETMASK is being set. If only address is supplied, the
following message is logged:
Waiting for DAD... Error: inet6 prefix is expected rather than
"2001:db8:ab:cd::12/"
and settle-dad.sh returns immediately, before DAD has settled.
'ip address list' appears to ignore the netmask if it is supplied, so
settle-dad could probably just use '[..] to "${IF_ADDRESS}"'.
Alternatively, 'netmask' could be documented as 'required'.
