Sure you do. NTP caches the IP address, and BIND round-robins or
randomizes multiple addresses on one hostname.

Thus, if you have three pool.ntp.org lines in your /etc/ntp.conf, you get
three stable servers (until you restart the server, then you get
three different ones). We did not want to do this by default because we
didn't (yet?) ask the pool.ntp.org people whether that would be
acceptable. It's their servers, after all.
