DNS device name
The DNS device name is a representative name that can be used for addressing instead of an
IP address.
If a DNS device name is entered, it is communicated to the DHCP server so that the central
processing unit can be addressed with the name entered if the function is supported in the rel-
evant LAN. If no DNS device name is entered, the central processing unit can only be ad-
dressed using the assigned IP address.
NOTE!
If DHCP is active, a DNS device name should always be used so that the central processing
unit can also be addressed if the IP address is changed.
DNS-server
The DNS server responds to requests from the network seeking to convert a DNS device name
into an IP address.
This IP address must be known if the central processing unit uses a representative name to
address a device or server (for example when sending an e-mail).
A valid IP address that is entered here is always used, even if the DHCP server provides a dif-
ferent DNS server address. If this is not the case, the DNS server address received from the
DHCP server is used (DHCP must be active).
