18.1 DNS
Each device in a TCP/IP network is usually located by its IP address. Because host names
are often used in networks to reach different devices, it is necessary for the associated IP
address to be known. This task can be performed by a DNS server, which resolves the
host names into IP addresses. Alternatively, name resolution can also take place over the
HOSTS file, which is available on all PCs.
Your device offers the following options for name resolution:
• DNS Proxy, for forwarding DNS requests sent to your device to a suitable DNS server.
This also includes specific forwarding of defined domains (Forwarded Domains).
• DNS cache, for saving the positive and negative results of DNS requests.
• Static entries (Static Hosts), for manually defining or preventing assignments of IP ad-
dresses to names.
• DNS monitoring, for providing an overview of DNS requests on your device.
Global Name Server
The IP addresses of global name servers that are queried if your device is unable to an-
swer requests itself or by forwarding entries are entered in Local Services -> DNS ->
Global Settings -> Basic Parameters.
