Of course you have IPv6, probably in the form of SLAAC/RA. How else Linux kernel used in the installer would know which IPv6 address to use and which IPv6 route to choose to 2001:41d0:202:100:213:32:5:7. > Is there some way > of telling the installer not to use IPv6? I have read > https://wiki.debian.org/DebianIPv6#How_to_turn_off_IPv6 but the > installer does not have file /etc/sysctl.conf Yet what installer *does* have that's /proc. So, wait for the network autoconfiguration, switch to root vt, invoke: echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6 And you just disabled IPv6 until the next reboot. Reco
