While release 4.4.2 is primarily a maintenance release that addresses a number
of defects, it does introduce a few new features:
- Keama - Keama is a migration utility that assists in converting ISC DHCP
server configuration files to Kea configuration files. It is found in the
keama subdirectory and includes a README.md file with instructions on how
to build it as well as a manpage on its usage.
- Two new server parameters related to ping checking were added:
1. ping-cltt-secs which allows the user to specify the number of seconds
that must elapse since CLTT before a ping check is conducted.
2. ping-timeout-ms which allows the user to specify the amount of time the
server waits for a ping-check response in milliseconds rather than in
In general, the areas of focus for ISC DHCP 4.4 were:
1. Dynamic DNS additions
2. dhclient improvements
3. Support for dynamic shared libraries
Dynamic DNS Improvements:
- We added three new server configuration parameters which influence DDNS
1. ddns-dual-stack-mixed-mode - alters DNS conflict resolution behavior
to mitigate issues with non-compliant clients in dual stack environments.
2. ddns-guard-id-must-match - relaxes the DHCID RR client id matching
requirement of DNS conflict resolution.
3. ddns-other-guard-is-dynamic - alters dual-stack-mixed-mode behavior to
allow unguarded DNS entries to be overwritten in certain cases
- The server now honors update-static-leases parameter for static DHCPv6
- We've added three command line parameters to dhclient:
1. --prefix-len-hint - directs dhclient to use the given length as
the prefix length hint when requesting prefixes
2. --decline-wait-time - instructs the client to wait the given number
of seconds after declining an IPv4 address before issuing a discover
3. --address-prefix-len - specifies the prefix length passed by dhclient
into the client script (via the environment variable ip6_prefixlen) with
each IPv6 address. We added this parameter because we have changed the
default value from 64 to 128 in order to be compliant with RFC3315bis
draft (-09, page 64) and RFC5942, Section 4, point 1.
**WARNING**: The new default value of 128 may not be backwardly compatible
with your environment. If you are operating without a router, such as
between VMs on a host, you may find they cannot see each other with prefix
length of 128. In such cases, you'll need to either provide routing or use
the command line parameter to set the value to 64. Alternatively you may
change the default at compile time by setting DHCLIENT_DEFAULT_PREFIX_LEN
- dhclient will now generate a DHCPv6 DECLINE message when the client script
indicates a DAD failure
Dynamic shared library support:
Configure script, configure.ac+lt, which supports libtool is now provided
with the source tar ball. This script can be used to configure ISC DHCP
to build with libtool and thus use dynamic shared libraries.
- The server now supports dhcp-cache-threshold for DHCPv6 operations
- The server now supports DHPv6 address allocation based on EUI-64 DUIDs
- Experimental support for alternate relay port in the both the server
and relay for IPv4, IPv6 and 4o6 (see: draft-ietf-dhc-relay-port-10.txt)
