Siemens SCALANCE XM-400 Configuration Manual page 155

If there is more than one DNS server, the order in the table specifies the order in which the
servers are queried. The top server is queried first. In total 5 DNS servers can be configured
on the IE switch. Manually configured DNS servers are given preference.
The DNS () server (Domain Name System) assigns a domain name to an IP address so that
a device can be uniquely identified.
If this function is enabled, the IE switch can communicate with a DNS server as a DNS client.
You have the option of entering names in IP address boxes.
Note
The DNS client function can only be used if there is a DNS server in the network.
