Default Gateway
This is the network address the components send data packets to, if the target
address is not in their own network, and no information is available as to how the
target network can be reached.
• It provides information on how the target network is reached or
• it forwards the packets to its default gateway in the next instance.
The default gateway can be compared to a standard exit. All requests that are
not directed to a device's own subnet are forwarded via the default gateway to
another network For example, the requests can then be directed to the internet.
Example: 192.168.0.1
Dynamic Host Conguration Protocol (DHCP)
• Is used to automatically congure IP addresses
of a network component
• This function is taken over by a router.
As soon as a component responds after activation using the so-called DHCP request,
the DHCP server responds and assigns to the component an IP address from a
previously dened IP address range. Apart from the IP address, a subnet mask,
a default gateway and, if required, a DNS address and lease time are assigned.
The domain name server translates the IP address into a computer name.
The lease time is used to determine for how long a network node receiving its IP
address dynamically from the DHCP server can keep that IP address.
