The document discusses IP addresses and the differences between IPv4 and IPv6. It defines what an IP address is, its uses, and the classes and addressing in IPv4. It describes problems with IPv4 like limited address space. It then defines IPv6 addressing which uses 128-bit addresses written in hexadecimal, and types of IPv6 addresses. It lists advantages of IPv6 like larger address space and built-in security. Tables compare features of IPv4 and IPv6 like address space, header fields, and representation.

IP?

6. What is the use of IP?
IP address works at the network layer of the OSI model.
Without IP addresses, devices on different networks will not
be able to communicate.
Every device needs a unique IP address in order to connect
to the internet.

7. IPv4 (IP Version 4)
32 bit, represented in 4 decimal number, each decimal
number is of 8 bit, separated by a dot(.).
Consists of 2 components.
#Network id # Host id.
IPv4 allows 232
.
Which section show the machine or host id depend on the
class network.

9. IPv4 address:
There are 5 different class in IPv4
Class Uses Start IP End IP CIDR
Class A Large networks 0 127 /8
Class B Medium networks 128 191 /16
Class C Small networks 192 223 /24
Class D Multicast 224 239 N/A
Class F Experimental
purpose
240 255 N/A

10. Problems in IPv4
Insufficiency.
Hard to configure
Overloaded NAT.
security issues.

11. IPv6 (IP Version 6)

12. Why IPv6?
32-bit address space soon to be completely allocated.
Header format helps speed processing/forwarding
Header changes to facilitate QoS

13. IPv6 Address Representation
xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
Each x is a 4bit hexadecimal digit
IPv6 addresses range from
0000:0000:0000:0000:0000:0000:0000:0000 to
FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF
