Package: dhcpcd Version: 1:9.4.1-24~deb12u4 Severity: normal X-Debbugs-Cc: d...@darkboxed.org
Hi Martin, I was just looking through my dhcpcd.conf again and was reminded that I've had to set `noipv4ll` very early on when starting to use dhcpcd and I've had it ever since. Now that I think about it I also remember complaints from collegues about this feature breaking their systems at very inopportune times. I think we should disable IPv4LL for trixie. IPv6 link-locals perform the same function but with less breakage since arguably more software is used to them being enabled. Since RFC 6540 "IPv6 Support Required for All IP-Capable Nodes" is a thing I don't see any point in having this legacy feature enabled by default. Ofc. I don't remember exactly what the problems with it were right now, but I'll probably remember later if I think about it a while. IIRC it was something to do with software incorrectly thinking the machine is online due to the IPv4LL address/route, but I'm not sure. --Daniel
