15.3. Debian Linux

1. Be sure that IPv6 is loaded, either because it is compiled into the kernel or because the module is loaded. For the latest, three solutions, adding it to /etc/modules, using the pre-up trick shown later or using kmod (not detailed here).

2. Configure your interface. Here we assume eth0 and address (2001:0db8:1234:5::1:1). Edit /etc/network/interfaces:

iface eth0 inet6 static
        pre-up modprobe ipv6
        address 2001:0db8:1234:5::1:1
        # To suppress completely autoconfiguration:
        # up echo 0 > /proc/sys/net/ipv6/conf/all/autoconf
        netmask 64
        # The router is autoconfigured and has no fixed address.
        # It is magically
        # found. (/proc/sys/net/ipv6/conf/all/accept_ra). Otherwise:
        #gateway 2001:0db8:1234:5::1

And you reboot or you just

# ifup --force eth0

and you have your static address.
