dhcpy6d - MAC address aware DHCPv6 server
[ -c file

is an open source server for DHCPv6, the DHCP protocol for IPv6.
Its development is driven by the need to be able to use the existing IPv4
infrastructure in coexistence with IPv6. In a dualstack scenario, the existing
DHCPv4 most probably uses MAC addresses of clients to identify them. This is
not intended by RFC 3315 for DHCPv6, but also not forbidden. Dhcpy6d is able
to do so in local network segments and therefore offers a pragmatical method
for parallel use of DHCPv4 and DHCPv6, because existing client management
solutions could be used further.
comes with the following features:
* identifies clients by MAC address, DUID or hostname
* generates addresses randomly, by MAC address, by range or by given ID
* filters clients by MAC, DUID or hostname
* assigns multiple addresses per client
* allows one to organize clients in different classes
* stores leases in MySQL or SQLite database
* client information can be retrieved from database or textfile
* dynamically updates DNS (Bind)
* supports rapid commit
* listens on multiple interfaces
Most configuration is done via the configuration file.
- -c, --config=configfile
- Set the configuration file to use. Default is
- -u, --user=user
- Set the unprivileged user to be used.
- -g, --group=group
- Set the unprivileged group to be used.
- -r, --really-do-it=yes|no
- Really activate the DHCPv6 server. This is a precaution to
prevent larger network trouble.
- -d, --duid=group
- Set the DUID for the server. This argument is used by
- -G, --generate-duid
- Generate DUID to be used in config file. This argument is
used to generate a DUID for /etc/default/dhcpy6d. After generation dhcpy6d
