Not generally. For some reason each lookup of any of these always 
returns 3 addresses. Since we still recommend four servers (even if 
there is some dispute over the reasons), using just pool.ntp.org won't 
work. Even is you do multiple lookups, if there is anything that does 
any caching in between you and the DNS server that sets the addresses, 
you will get the same three.

I don't know why there are only three addresses. The simplest solution 
would be for the round robin DNS servers to give out more addresses, 
then you could just have the single line.
