automatically its DHCP Server, distributing IP-Addresses from 192.168.1.2 to
192.168.1.50 with a Maximum Lease Time of 1 day. This behavior ensures an easy auto
configuration of the IB-NAS2001-B in a Network with no auto configuration
infrastructure.

In a TCP/IP based Network a computer can send directly data only to other computers in it’s own subnet. To be able to send
data to other computers, a rooter is necessary to link this subnet to the rest of the network and all computers in the subnet
need to know its IP Address because they will send all data for destinations out of their subnet to the rooter to be forwarded.
This IP Address of the router is defined by the default gateway setting.

DNS is the acronym for “domain name service”. This names a process of assigning internet names to IP Addresses. The DNS
server is comparable to a telephone book. At this server all internet applications look up the referring IP Address for an internet
name. Without that service or when the DHCP server doesn’t know the internet name, the internet name could not be used to
address a host or device. The only chance to get access to that host or device is to use the IP Address directly.
