Hi! I installed CentOS 7 today, it's a minimal install, so it didn't have ifconfig command. So I installed net-tools, however I can't add ipv6 address to it. # ifconfig enp0s3 add fc00::1002/124 SIOCSIFADDR: Permission denied. Yes, I'm running as root. CentOS is running in a Qemu instance with e1000 ethernet card.
