|
A special address used to send data to all hosts in the network
|
|
|
What is a Unicast?
|
the process of sending a packet from one host to an individual host
|
|
|
What is a broadcast?
|
the process of sending a packet from one host to all hosts in the network
|
|
|
What is a multicast?
|
the process of sending a packet from one host to a selected group of hosts
|
|
|
Some examples for using broadcast transmission are:
|
Mapping upper layer addresses to lower layer addresses
Requesting an address Exchanging routing information by routing protocols |
|
|
What is a directed broadcast?
|
A directed broadcast is sent to all hosts on a specific network. eg. 172.16.4.255
|
|
|
What is a limited broadcast?
|
The limited broadcast is used for communication that is limited to the hosts on the local network. eg. 255.255.255.255
|
|
|
Some examples of multicast transmission are:
|
Video and audio distribution
Routing information exchange by routing protocols Distribution of software News feeds |
|

|
What is the IPv4 multicast address range?
|
224.0.0.0 to 239.255.255.255
|
|
|
What is the IPv4 host address range?
|
0.0.0.0 to 223.255.255.255
|
|
|
The IPv4 private address blocks are?
|
* 10.0.0.0 to 10.255.255.255 (10.0.0.0 /8)
* 172.16.0.0 to 172.31.255.255 (172.16.0.0 /12) * 192.168.0.0 to 192.168.255.255 (192.168.0.0 /16) |

|
127.0.0.1
|
|
|
What is the range of Link Local Addresses?
|
169.254.0.0
169.254.255.255 |
|
|
What is the range of TEST-NET addresses?
|
192.0.2.0
192.0.2.255 |
|
|
The allocation of addresses inside networks should be planned and documented for the purpose of:
|
* Preventing duplication of addresses
* Providing and controlling access * Monitoring security and performance |
|
|
What is the minimum configuration required for statically assigned addresses?
|
* Host IP address
* Subnet mask * Default gateway |
|
|
Other issues were also considered during the development of IPv6, such as:
|
* Improved packet handling
* Increased scalability and longevity * QoS mechanisms * Integrated security |
|
|
IPv6 offers:
|
* 128-bit hierarchical addressing
* Header format simplification * Improved support for extensions and options * Flow labeling capability - as QoS mechanisms * Authentication and privacy capabilities - to integrate security |
