15.1 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 asso-
ciated IP address to be known. This task can be performed by a DNS server, which re-
solves 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), to manually define or prevent assignments of IP addresses
to names.
• DNS monitoring (statistics), to provide an overview of DNS requests on your device.
