Strange ip and interfaces on pihole network, i don't understand

[Kykkus]

Expected Behaviour:

All device in eth0 and with a visible ip

Actual Behaviour:

there are eth0 and eth0@if14 that i don't what is and there is an entry with no ip and no interface

Debug Token:

in pihole 6 i don't find that option.

Explanation of doubts:

Hi everyone, if I look at network I find things that I don't understand:

ip pihole is 192.168. 55.55 (in a docker).
eth0 is where all the devices of the network interface to the pihole.

• What is "eth0@if14"?
• Why is there an entry of "ip-::" at interface "N/A"?

I don't understand, can you explain to me please?
(I tried to attach the log, but in version 6 I can't find the entry export pihole.log anymore)
Thanks for your attention and for those who will want to answer me and explain to me

I Pi-hole v6 debug logs cannot be generated in the web interface anymore. Please generate it with

docker exec -it <pihole-container-name-or-id> pihole -d

and upload just the token.

Thanks for the reply and the trick!
Here is the debug token:

eth0@if14 is the name of the interface inside your docker container.

If you execute ip address inside the container you will see only lo and eth0@if14. This is normal when using macvlan.

Try it:

docker exec -it <pihole-container-name-or-id> ip a

Don't see eth0@if14 in your suggest command...
And also what is entry ip-::?

Thanks a lot for giving to me you time and your knowledge

ip a

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0@if14: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether 26:90:6d:82:c9:7a brd ff:ff:ff:ff:ff:ff
    inet 192.168.55.55/25 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::2490:6dff:fe82:c97a/64 scope link
       valid_lft forever preferred_lft forever

EDIT:

I see now if14 lol, thanks,

For the other queston?

[Kykkus]

Nobody can explain me:

Why is there an entry of "ip-::" at interface "N/A"?

Thanks!

:: is the IPv6 loopback address. For all devices for which Pi-hole does not get a MAC address (because there is no entry in the neight cache) it 'creates' a mock hardware address starting withip- and followed by the IP address.
