"Changes since 4.1.0 (new features)
- The 'hardware [ethernet|etc] ...;' parameter in host records has been
extended to attempt to match DHCPv6 clients by the last octets of a
DUID-LL or DUID-LLT provided by the client."
This feature was added in DHCP 4.2.0, but RedHat has backported this change
to the 4.1.x version distributed with RHEL6.2.
