# Entering Server Pool IP addresses for your DNS Server

When using static DNS entries (recommended), you must make sure that the IP addresses for your Server Pool are properly entered into your DNS server’s records.

The Server Pool has one IP address for each NetLink (Internet connection) in a Multi-Link configuration and a single IP address in a single-link configuration. If you decide to use dynamic DNS updates, you must configure the DNS server to accept the DDNS updates from the engine. If the servers have multiple IP addresses, make sure the IP addresses are all defined on the DNS server to ensure operation as intended.

See the documentation of your DNS server software for instructions on how to enter the IP addresses.
