    No IPV6 related entries Though since the kernel supports it, I
    could configure them at will without reboot. I'd bet you could
    replicate this on any FreeBSD machine by:

    ifconfig interfaces inet6 addresses -alias
    route delete -inet6 routes

    Don't forget lo0.

    I get the same SERVFAIL error only for one particular domain
    I run Linux (Ubuntu 6.10)

    That's more likely to be a problem with the domain or its delegations.
