I'm running BusyBox 1.24.1 on Alpine Linux. When I bring up networking with
"ip link set eth0 up", I get IPv6 addresses via SLAAC, as expected. To get
an IPv4 address as well, I start udhcpc with "udhcpc -R -n -p
/var/run/udhcpc.eth0.pid -i eth0 -x hostname:alpine". As soon as I run this
command, I get an IPv4 address, as expected, but all IPv6 addresses are
removed from the interface. How can I obtain an IPv4 address from DHCP
without losing my IPv6 addresses from SLAAC?
