dhcpcd for IPv6 + old static IPv4 setup not working well together
Sorry if I'm missing something obvious. Searching on this stuff isn't so easy.
I have a long running NetBSD/i386 machine that was set with a static
IPv4 address and ip6mode=host in /etc/rc.conf. I upgraded it to the
most recent release-8 from nyftp.netbsd.org a few days ago.
Recently I decided to allow it to be autoconfigured for IPv6 via
router advertisement. So I set ip6mode=autohost, dhcpcd=YES. This
configures IPv6 but it also adds an APIPA IPv4 address and broke the
default gateway (none defined in netstat -r even though /etc/mygate
exists). So I added dhcpcd_flags="-6" to /etc/rc.conf. This removed
the APIPA address and the default route exists again. By the way, I'm
rebooting each time I make a change to /etc/rc.conf.
My current problem is /etc/resolv.conf only contains IPv6 DNS servers
advertised from my router, even though a previous /etc/resolv.conf
exists with a valid IPv4 DNS server. Actually, I don't know if this is
a problem, DNS is working with the IPv6 server. But I wonder if this
is correct behavior?
It seems like I'm doing this wrong and there is a better way for IPv6
autoconfig and IPv4 static setup to coexist. Am I?
