When checking the logs, they're flooded with "deleting address". 

Here's a bit of those logs:

I've redacted my IPV6 addresses. Couldn't find a tool for that, so I simply replaced parts of it by variables, where I saw them repeating ¯\_(ツ)_/¯  

 

Here's what my settings look:

Interface eth0

IPv6 address assignment: Automatic

IPv6 address: [PART1]:[PART2] / 64

IPv6 default gateway: fe80::[GATEWAY-ADDRESS]

IPv6 privacy extensions: Disabled

IPv6 DNS server assignment: Automatic

IPv6 DNS server: fd00::[GATEWAY-ADDRESS]

IPv6 DNS server 2: [PART1][GATEWAY-ADDRESS]

Desired MTU: 1500

Enable VLANs: No

 

Interface Extra

Current listening interfaces: br0

Include listening interfaces: -empty-

Exclude listening interfaces: -empty-

 

Routing Table

ROUTE  -  GATEWAY  -  METRIC

IPv4

default  -  192.168.178.1 via br0  -  0

172.22.0.0/16  -  br-9a649b6f5d31  -  0

192.168.178.0/24  -  br0  -  1

 

IPv6

[PART1]::/64  -  br0  -  1005

[OTHER-ADDRESS]::/64  -  br0  -  1005

default  -  fe80::[GATEWAY-ADDRESS] via br0  -  1005

    What VARIABLES ? ? ?

    You used "automatic" for the interface (which is totally correct!). This means, all fields are filled out automatically. No PART1 or PART2!

     

    The messages come from "dhcpd", this is not installed by default, and also not needed for V6 operations. It conflicts with the router's announcements (fields are doubled, usually creates a mess).

    So you better uninstall dhcpd fast, this will also get you rid of the messages.

    By variables I meant that I replaced the same numbers in my logs with the same words, to anonymise my IPs

     

    Not sure where "dhcpcd" would be coming from then. I have these Plugins installed:

    I checked NerdTools and it isn't installed there (not even listed there).

    still got the problem, though it looks like it's not only spamming deletions now:

      

    Feb 16 12:39:43 OddNas avahi-daemon[17573]: Registering new address record for ADDRESS on br0.*.
Feb 16 12:39:47 OddNas dhcpcd[1016]: br0: deleting address ADDRESS/64
Feb 16 12:39:47 OddNas avahi-daemon[17573]: Withdrawing address record for ADDRESS on br0.
Feb 16 12:41:36 OddNas dhcpcd[1016]: br0: deleting address ADDRESS/64

    dhcpcd comes, afaik installed by default. I wasn't able to find anything saying otherwise.

     

    For now I've just disabled IPv6, would love to find a real solution to this
