Static IPv6 Fallback not getting enabled when DHCPv6 and SLAAC is disabled

fallback static_ipv4

profile static_ipv4
static ip_address=10.xxx.xxx.100/24
static routers=10.xxx.xxx.101
static domain_name_servers=8.8.8.8 1.1.1.1

fallback static_ipv6

profile static_ipv6
static ip6_address=2001:xxxx:xxxx:xxxx::10/64
static ip6routers=2001:xxxx:xxxxx:xxxx::2`

Could it be that my static_ipv6 profile is not getting triggered?
My intended aim is to make dhcpcd.conf file work for 4 cases

Case 1: DHCPv4 and DHCPv6 works, get dynamic IPv4 and IPv6 (successful)

Case 2: DHCPv4 does not work and DHCPv6 works, set static IPv4 and get dynamic IPv6 (successful)

Case 3: DHCPv4 works and DHCPv6 does not works, get dynamic IPv4 and set static IPv6 (unsuccessful as static IPv6 is not set)

Case 4: DHCPv4 does not work and DHCPv6 does not works, set static IPv4 and IPv6 (unsuccessful as static IPv6 is not set)

Also this is version 8.1.2 running on debian raspi (linux 11)

Debian stable has 9.4.1 and testing currently has 10.1.0. You might wanna test using one of these instead.

fallback is currently only for DHCP, not DHCPv6.

Ok thanks for the confirmation

[Kenny-a11y]

also quick question what is the line i should add to to let me add a ipv6 dns server? I want to it to append it to resolv.conf

[rsmarples]

dhcpcd doesn't support prefixing/appending configs directly.

But you have a few options:

• Massage the new_dhcp6_name_servers variable in dhcpcd.enter-hook
• Configure resolvconf(8) to do append any dns server you want
