I have experienced the same thing. When the DHCP server tries to
update the A record of a dual-stacked client the TXT records seem to
get in the way. Could this have something to do with DHCPv6 not using
mac addresses and using DUIDs instead? I wonder how the DHCID is
computed for a IPv6 TXT record?
We have two sets of DHCP servers which handle either IPv4 or IPv6 as
the first response mentioned.
