Hm, I've got an Ubuntu 8.10 machine here which AFAIK is also based on Debian but also returns both the IPv4 and IPv6 addresses by default: # host support.ntp.org support.ntp.org has address 204.152.184.138 support.ntp.org has IPv6 address 2001:4f8:0:2::23 Our local DNS server running bind-9.3.1 is authoritative for our internal domain, and forwarding other requests to DNS servers on the internet.
