Dhcpv6 e v4

[Marcelo Magno Espindola de Melo]

I would like to know how it is possible to use dhcp to provide ipv4 and ipv6 at the same time

You have to run two instances - at least with the ISC server.
One instance deals with IPv4.
Another instance deals with IPv6. For IPv6, you must also run a Router Advertisement service on your routers, and set the flags (IIRC you must set the Managed flag) to tell the devices to use the DHCP server to obtain addresses - otherwise they will just use SLACC and never ask the DHCP server for an address.

As with ISC dhcpd you would have to run 2 instances, one for every
protocol, you could as well run dhcpd for IPv4 and our DHCPv6 server
dhcpy6d for IPv6. See https://dhcpy6d.ifw-dresden.de for details.

You would have two config files.  One for dhcp 4 and one for dhcp 6.  Then you would execute something like this:

dhcpd -cf /etc/dhcp4.conf

dhcpd -6 -cf /etc/dhcp6.conf

The key there is the -6 to tell dhcpd to run DHCPv6.

You also may want to look at specifying the lease files.  Those need to be separate as well, so maybe something like this:

dhcpd -cf /etc/dhcp4.conf -lf /var/state/dhcp/dhcpd4.leases

dhcpd -6 -cf /etc/dhcp6.conf -lf /var/state/dhcp/dhcpd6.leases

I'm sure people on this list would be happy to help with specific config file questions if you struggle making the configuration files.
