isc-dhcp-server 4.4.1

[Samuel Motta]

Hi folks, I installed isc-dhcp-server 4.4.1 version on a Debian 11 and it
does not work here.

*here my ifconfig parse that show that I does not use ipv6*

enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.0.3  netmask 255.255.255.0  broadcast 192.168.0.255

I´m trying to force *isc-dhcp-server* to only start the v4 instance with
INTERFACESv4 option that is the new directive

if I try to use interfaces directive like older versions syslog show me to
use INTERFACESv4 OPTION but it migrate automatically for now.


Feb 23 13:30:25 debian-backup isc-dhcp-server[388886]: DHCPv4 interfaces
are no longer set by the INTERFACES variable in

/etc/default/isc-dhcp-server.  Please use INTERFACESv4 instead.

*here my syslog (still trying load dhcpd6.conf but lauch IPv4 server only
that it is what I need.)*
