Calculating Network,Host & Broadcast Address

10. IPv4 Types of communication in IPv4 network :
Unicast - the process of sending a packet from one host to an individual host
Broadcast - the process of sending a packet from one host to all hosts in the network
Multicast - the process of sending a packet from one host to a selected group of hosts

11. IPv6
Creating expanded addressing capabilities was the initial motivation for developing this new protocol.
Other issues were also considered during the development of IPv6, such as:
Improved packet handling
Increased scalability and longevity
QoS mechanisms
Integrated security

12. IPv6 To provide these features, IPv6 offers:
128-bit hierarchical addressing - to expand addressing capabilities
Header format simplification - to improve packet handling
Improved support for extensions and options - for increased scalability/longevity and improved packet handling
Flow labeling capability - as QoS mechanisms
Authentication and privacy capabilities - to integrate security

15. IP Public & IP Private
Although most IPv4 host addresses are public addresses designated for use in networks that are accessible on the Internet, there are blocks of addresses that are used in networks that require limited or no Internet access.
These addresses are called private addresses.

16. IP Public & IP Private The private address blocks are:
to ( /8)
to ( /12)
to ( /16)

17. IP Public & IP Private

18. IP Public & IP Private NAT (Network Address Translasion) :
With services to translate private addresses to public addresses, hosts on a privately addressed network can have access to resources across the Internet.
These services, called Network Address Translation (NAT), can be implemented on a device at the edge of the private network.
NAT allows the hosts in the network to "borrow" a public address for communicating to outside networks.

19. IP Public & IP Private IP Public :
The vast majority of the addresses in the IPv4 unicast host range are public addresses.
These addresses are designed to be used in the hosts that are publicly accessible from the Internet.

21. Ip Static & ip Dynamic
IP Static :

22. Ip Static & ip Dynamic IP Static : Advantages : Disadvantage :
With a static assignment, the network administrator must manually configure the network information for a host.
Advantages :
they are useful for printers, servers, and other networking devices that need to be accessible to clients on the network.
increased control of network resources.
Disadvantage :
it can be time-consuming to enter the information on each host.

23. Ip Static & ip Dynamic
IP Dynamic

24. Ip Static & ip Dynamic IP dynamic : Advantages :
Because of the challenges associated with static address management, end user devices often have addresses dynamically assigned, using Dynamic Host Configuration Protocol (DHCP).
DHCP enables the automatic assignment of addressing information such as IP address, subnet mask, default gateway, and other configuration information.
Advantages :
DHCP is generally the preferred method of assigning IP addresses to hosts on large networks because it reduces the burden on network support staff and virtually eliminates entry errors.
DHCP not permanently assigned to a host but is only "leased" for a period of time.
