On recent versions of FreeBSD, the isc-dhcpd-server package installs two rc scripts, which are used to run the two instances of the daemon we’ll have to run. # Sample configuration file for ISC dhcpd for Debian / Ubuntu At present, the ISC DHCP daemon can’t run in both IPv4 and IPv6 modes simultaneously. I personally prefer to run the dhcp process on a linux system and relay it for both v4 and v6.Īssuming you are installing isc-dhcpd, the following configurations can be used to delegate host addresses for both IPv4 and IPv6 It's a 14 byte long identifier, starting with a 2 byte length information (usually ”0x000e”): # hexdump -e '"%07.When deploying dual stack, dhcpv6 is a crucial piece of the puzzle. Note that the ”dhcp.client-id” no longer belongs to a MAC address, an unique ID is used instead! ”dhcp6c” (see above) uses the file /var/lib/dhcpv6/dhcp6c_duid (would be created during first start, if not existing) as unique identity.
# Prefix range for delegation to sub-routers Option dhcp6.domain-search "domain.example" # Range for clients requesting a temporary address Note, that the router requires to have a interface configured with an IPv6 address out of the defined subnet. Create a dedicated configuration file /etc/dhcp/nf for the IPv6 part of the dhcpd.
