What are some address types?
|
Local
Global Private Public Persistent(Static) Temporary(DHCP) |
|
What is Local Addressing?
|
Not advertiesed outside local network.
E.G. Link Layer Addressing |
|
What is Global Addressing?
|
Addresses that are recognised world wide.
For E.g. Such addresses are usually at the network IP layer |
|
What is Private Addressing?
|
Addresses that are not routed thorugh the public network
For e.g NAT (Network Address Translation) |
|
What are Public Addresses?
|
Network layer addresses that are routed through the public internet.
|
|
Temorary addresses are?
|
Addresses temporarly assigned. (Dynamically via DHCP)
|
|
What type of address is permenantly configured within the device?
|
Persistant/Static Address
|
|
Describe the purpose of routing?
|
Learning the reachabilty information to forward ip packets to their intended destination.
|
|
What is Reachability?
|
How the router can reach other networks. For e.g through routing tables. Reachability can be learned statically or dynamically.
|
|
Describe 2 fundamentals of addressing.
|
Indentifyer(IP) and the subnetmask
|
|
What is a subnet masks function?
|
255.255.255.0 specifies that the network portion is the first 3 octects due to the 255 filling each octet.
For example: 192.168.1 is part of the network. Numbers specifies after this is the host/device number on that network. |
|
ANDING allows you to decide what?
|
Which network a device is located on. To perform this convert the IP of the network device into its binary format and the subnet of the network into its binary format then complete a Logical AND.
1 AND 1 = 1 1 AND 0 = 0 0 AND 0 = 0 |
|
Routing fundamentals include?
|
Learning reachability within and between networks
Reachabilty information is used to forward ip packets Learn approachability statically and dynamically. |
|
Purpose of a Routing Table?
|
Determines how packets can reach other network and what is the best path.
|
|
How does a router foward packets?
|
It determines the network portion, from the it compares the destination of the packet to its routing table and chooses the best route.
