 Calculating Network,Host & Broadcast Address
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
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
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

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.
IP Public & IP Private
 The 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)
IP Public & IP Private
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.
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.

IP Static & IP Dynamic
 IP Static :
IP Static & IP Dynamic
 IP Static :
 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.
IP Static & IP Dynamic
 IP Dynamic
IP Static & IP Dynamic
 IP dynamic :
 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.
