IPv4 |
IPv6 |
|
IPv4 has a 32-bit address
length |
IPv6 has a 128-bit address
length |
|
It Supports Manual and DHCP address
configuration |
It supports Auto and
renumbering address configuration |
|
In IPv4 end to end,
connection integrity is Unachievable |
In IPv6 end-to-end,
connection integrity is Achievable |
|
It generates 4 billion unique addresses |
It generates 340 undecillion unique addresses. |
|
The Security feature is
dependent on the application |
IPSEC is an inbuilt security
feature in the IPv6 protocol |
|
Address representation of
IPv4 is in decimal |
Address representation of
IPv6 is in hexadecimal |
|
Fragmentation performed
by Sender and forwarding routers |
In IPv6 fragmentation is
performed only by the sender |
|
In IPv4 Packet flow
identification is not available |
In IPv6 packet flow
identification are Available and uses the flow label field in the header |
|
In IPv4 checksum field is
available |
In IPv6, the checksum field
is not available |
|
It has a broadcast Message
Transmission Scheme |
In IPv6 multicast and anycast
message transmission scheme is available |
|
In IPv4 Encryption and
Authentication facility not provided |
|
|
IPv4 has a header of 20-60
bytes. |
IPv6 has a header of 40 bytes
fixed |
|
IPv4 can be converted to IPv6 |
Not all IPv6 can be converted
to IPv4 |
|
IPv4 consists of 4 fields
which are separated by addresses dot (.) |
IPv6 consists of 8 fields,
which are separated by a colon (:) |
|
IPv4’s IP addresses are
divided into five different classes. Class A, Class B, Class C, Class D,
Class E. |
IPv6 does not have any
classes of the IP address. |
|
IPv4 supports VLSM( Variable Length Subnet Mask). |
IPv6 does not support VLSM. |
|
Example of IPv4:
66.94.29.13 |
Example of IPv6:
2001:0000:3238:DFE1:0063:0000:0000:FEFB |

Private
IP Address |
Public
IP Address |
|
The scope of Private IP is local. |
The scope of Public IP is global. |
|
It is used to communicate within the network. |
It is used to communicate outside the network. |
|
Private IP addresses of the systems connected in a network
differ in a uniform manner. |
Public IP may differ in a uniform or non-uniform manner. |
|
It works only on LAN. |
It is used to get internet service. |
|
It is used to load the network operating system. |
It is controlled by ISP. |
|
It is available free of cost. |
It is not free of cost. |
|
Private IP can be known by entering “ipconfig” on the command
prompt. |
Public IP can be known by searching “what is my ip” on Google. |
|
Range: 10.0.0.0 – 10.255.255.255, 172.16.0.0 – 172.31.255.255, 192.168.0.0 – 192.168.255.255 |
Range: Besides
private IP addresses, the rest are public. |
|
Example: 192.168.1.10 |
Example: 17.5.7.8 |
|
Private IP uses numeric code that is not unique and can be used
again |
Public IP uses a numeric code that is unique and cannot be used
by other |
|
Private IP addresses are secure |
The public IP address has no security and is subjected to attack |
|
Private IP addresses require NAT to communicate with devices |
Public IP does not require a network translation |
|
The scope of Private IP is local. |
The scope of Public IP is global. |
|
Static
IP Address |
Dynamic
IP Address |
|
It is provided by ISP (Internet
Service Provider). |
While it is provided by DHCP
(Dynamic Host Configuration Protocol). |
|
Static IP address does not change
any time, it means if a static ip address is provided then it can’t be
changed or modified. |
While dynamic ip address
change any time. |
|
Static ip address is less
secure. |
While in dynamic ip address,
there is low amount of risk than static ip address’s risk. |
|
Static ip address is
difficult to designate. |
While dynamic ip address is
easy to designate. |
|
The device designed by static
ip address can be traced. |
But the device designed by
dynamic ip address can’t be traced. |
|
Static ip address is more
stable than dynamic ip address. |
While dynamic ip address is
less stable than static ip address. |
|
The cost to maintain the
static ip address is higher than dynamic ip address. |
While the maintaining cost of
dynamic ip address is less than static ip address. |
|
It is used where
computational data is less confidential. |
While it is used where data
is more confidential and needs more security. |
|
Simplifies the
troubleshooting as the ip is always the same. |
While dynamic ip increases
the complexity of diagnosing the network issues. |
