    In a single NIC configuration, does the BOOTPROTO have to be “static”, or can each be “dhcp” if reservations are on the DHCP server?

    I’ll answer my own question (perhaps) with an assumption of yes, since a DHCP server won’t be able to farm out to IP’s to the same MAC… true?

    Hi! Please tell me how to configure ipv6 for different interfaces without using the settings interface ipv4, is it possible at all on centos?
    n the interface settings should I prescribe the following:
    DEVICE=eth0:0
    BOOTPROTO=static
    ONBOOT=yes
    IPV6INIT=yes
    IPV6ADDR=2a01:230:2:6::9eb/64

    but the resulting console responds:
    error in ifcfg-eth0:0: didn’t specify device or ipaddr
