@thor @lamp @thor @lamp it's literally just an additional ip address on the interface, you don't need to worry about the kernel part of the network stack

you can remove the offending ip address from the interface with the usual tools. if the ip was retrieved via dhcp you can edit the config for your client. if it ended up there some other way then you'd need to figure out what did it obviously

but aside from being annoying as fuck to work with and having shitty tooling they're really nothing to worry about. it's really is just an additional ip address on the interface
