dhclient 4.3 will have an option to use/generate a DUID in "v4" mode.
https://kb.isc.org/article/AA-01073/82/DHCP-4.3.0a1-Release-Notes.html - Update the DDNS code to current standards and allow for sharing of DDNS entries between v4 and v6 clients. The new code is used if the ddns-update-style is set to "standard", the older code is still available if ddns-update-style is set to "interim". The oldest DDNS code "ad-hoc" has been removed. Thanks to Thomas Pegeot who submitted a patch for this issue. This patch is based on that work with some modifications.
