IP :- (Internet protocol) it is a 32bit
address which is divided into four object contains 8bit eg-8888=32. It addresses
& second ones is host address eg-10.0.0.10 here 10 - network address &
0.0.10 is host address.
Subnet Mark :- Subnet mask is a 32 bit address which
tell us that how many bits are used for network add & how many bits are
used for host add network bites always set to be one & host bit always set
to be zero.
Network bit - 1
Host bit - 0
IP ADDRESS CLASSES (Click on photo )
Two types of networks are => Private IP Address: - Free of cost used in the LAN.
Public IP Address: - Used to connect your LAN with WAN
Invalid and reserved IP address
1>we cannot use 10.0.0.0. Because it is a network address used
by the router.
2>All the host bit cannot be one, means 10.255.255.255 because
it is a 10th Network Broadcast IP address.
3>we cannot used 255.255.255 because it is an all network.
4>we can't use 0.0.0.0 because it is used for default routing.
5>we can’t use 127.0.0.1 because it is used for troubleshooting
purpose or also known as loopback IP.
ARIPA RANGE IP ADDRESS: -- Automatic Private Internet
Protocol Address
ARP BROADCASTING: - Address Resolution Protocol is a
standard primary method to resolve ip to mac address of the host computer
before any communication every computer perform ARP.
ARP used to complete the transaction of any file (IP
to MAC)
=> It will perform in four cases:-
* When one computer wants to communicate with in LAN in the same
network computer there he will perform ARP.
* When one computer want's to communicate with its own
internetwork computer by using router then he will perform router gateway
address.
*
When one router wants to forward the data on behave of its own client computer
by using its own router then both routers will perform ARP. But in case of two routers
Arp is none as proxy Arp.
=> When destination router wants to deliver the data in
that network computer then he will perform Arp with that computer ip address.
