What do the entries mean?
IP address IP netmask Time Distance Router
Local routing
Interaction of static and dynamic tables
IP masquerading NAT, PAT
Two addresses for the router
How does IP masquerading work?
Simple and inverse masquerading

DNS forwarding
Which protocols can be transmitted using IP masquerading?
Only small difference is that
Bridging

Automatic address administration with Dhcp
What are the filter options?
Dhcp client
Dhcp server
Cable modem really belongs to two LANs
IP address Network mask Broadcast address
Default state is auto
Dhcp on, off or auto?
How are the addresses assigned?
IP address assignment
Default gateway assignment
Network mask assignment
Broadcast address assignment
DNS server assignment
Priority for the Dhcp server Request assignment
Priority for a workstation-overwriting an assignment

IP address Netmask Remark
10.0.0.0 255.0.0.0
There are two considerations when using these IP addresses
IP routing and hierarchical IP addressing

Expansion through local networks
Why a LAN is called multiprotocol-capable
80-C7-6D-A4-6E
Easy as possible
That is processed by all computers in the LAN
Interface only understands MAC addresses
