The document discusses IP addresses and related networking concepts. It defines an IP address as a 32-bit logical address assigned to computers and networking devices to identify them on a network. IP addresses are divided into four octets with 8 bits each. The IANA manages global IP address space allocations. Private IP addresses are used for local networks and do not route over the public internet, while public IPs are required to access the internet. There are different classes of IP addresses that define ranges for different network sizes. IP version 6 is the next generation 128-bit IP addressing system currently under development.

Prepared by Prem Sahu

2. IP Address
It is 32bit logical address assign to Computer , Printer networking device such as Router to identify in network
It is divided in 4 octat having 8 bit
The Internet Assigned Numbers Authority (IANA) manages the IP address space allocations globally
E.g.
IP address: 192.168.1.7
Subnet Mask: 255.255.255.0
Default gateway: 192.168.1.1
DNS server: 192.168.1.5

3. IP4
Private IP: It is used to assign in Local Area Network which do
not route through internet or public network.
This is free and we don’t need to purchase this IP
Public IP: It is used for public network means internet use. It
route through internet and accessible from any location.
We have to purchase this IP from ICANN or domain reseller.

4. Class of IP
Class A: 1.0.0.0 to 126.255.255.254
Class B: 128.0.0.0 to 191.255.255.254
Class C: 192.0.0.0 to 223.255.255.254
Class D: 224.0.0.0 to 239.255.255.254
Class E: 240.0.0.0 to 254.255.255.254
Class D and class E is reserved for Scientific and research
organization.
IP 127.0.0.1 to 127.255.255.254 is used for loopback address

5. IP6
IP6(Internet Protocol version 6) This is next Gen
IP address which is steal to implement and it is under
Research and development(R&D)
It is 128 bit IP address and represent in hexadecimal

6. Default Gateway
It is entry or exit point of network which is assign to router to communicate
between two different network
Subnet Mass
It is assign to system to identify the class of IP and
find the number of host and network.

7. Assign IP Address in system
Double click in network icon- click in properties- Select Internet Protocol(TCP/IP)- Properties- select
use the following IP address and type the IP address, subnet mask, Default gateway, DNS server
Or
Open my network place- View network place- Select Local Area Network- Properties- Select Internet
Protocol(TCP/IP)- Properties- select use the following IP address and type the IP address, subnet mask,
Default gateway, DNS server

8. Check IP and Network Connection
Start- RUN- type cmd
type Ipconfig/all to see the IP address
type Ping 192.168.1.5 to test network connection

9. View IP address of System
Double click in network icon in taskbar- go to support tab, you can see the IP
address details.

10. View IP address of System
Double click in network icon in taskbar- go to support tab, you can see the IP
address details.
