Remote Gateway
Preferred Gateway
NAT Gateway
What two ways can a host receive addressing information?

Stationary
NAT
Routing is a Layer ______ function.

What does the characteristic of Best Effort mean for IP?
It's so good the packets will all get to their destination.
Some packets may get to the destination, some may not.
Packet delivery is guaranteed.
IP is the best protocol as far as the effort put into packet delivery.
Why is NAT necessary for IPv4?
There are not enough addresses available for all of the devices on the internet.
IPv4 cannot be used on the internet and must be translated to NAT.
In order for IPv6 to be used, current IPv4 addresses must be translated into IPv6 through NAT.
IPv4 addresses are Not All There (NAT) so NAT makes up for the deficiency by allowing all IPv4 addresses the be there.
