The "pool" configuration option in ntp.conf makes use of eventually available multiple ip adddresses specified in a A-record (example: 0.pool.ntp.org). The main difference to the "server" configuration it not just takes the first address to use as the time reference. As a result, a more reliable and flexible configuration can be achieved. Note: "man 5 ntp.conf" is not mentioning this configuration but /etc/ntp.conf.debian is using it.
