After digging a bit in codesearch, I think that this actually belongs to
the netcfg package. The error message encountered by Jens is still in
debian/netcfg-static.templates, in netcfg/bad_ipaddress, which is
invoked in various places inside static.c.
The line
debconf_set(client, "netcfg/get_netmask", "ffff:ffff:ffff:ffff::");
in netcfg_get_netmask strongly suggests that the original author
seriously thinks that this is a correct way to notate an IPv6 prefix
length.
