A routing table is a data file in RAM that is used to store route information about directly connected network. A router uses the information in the routing table to determine the best path to reach those destinations.
The default gateway is the device that routes traffic from the local network to devices on remote networks. Has a local IP address in the same address range as other hosts on the network. Can take data
in and forward data out.
A host can send a packet to: Itself - A host can ping itself by sending a packet to a special IPv4 address of 127.0.0.1 which is referred to as the loopback interface.
Local host - This is a host on the same network as the sending host. The hosts share the same network address.
Remote host - This is a host on a remote network. The hosts do not share the same network address.
Routing definition
Routing is the process of moving packets across a network from one host to a another. It is usually performed by dedicated devices called routers. Routing is the process of identifying the best path to a destination.
Advantages of IPv6
There is an improvement in the routing efficiency for performance and forwarding of packets. There is no requirement for routing process. Much more simplified than IPv4.
IPv6 comparison with IPv4
What are the changes in IPv6
There is an increased in IP address allocation. There is an improvement in packet handling. It eliminates the need for Network Address Translation.
