IPv4

  1. IPv4 (Internet Protocol Version 4)
  2. IPv6 (Internet Protocol Version 6)

Differences between IPv4 and IPv6

The address through which any computer communicates with our computer is simply called an Internet Protocol Address or IP address. For example, If we want to load a web page or we want to download something, we require the address for delivery of that particular file or webpage. That address is called an IP Address.

IPv4 address consists of two things that are the network address and the host address. It stands for Internet Protocol version four. It was introduced in 1981 by DARPA  and was the first deployed version in 1982 for production on SATNET and on the ARPANET in January 1983....

IPv6

IPv6 is based on IPv4 and stands for Internet Protocol version 6. It was first introduced in December 1995 by Internet Engineering Task Force. IP version 6 is the new version of Internet Protocol, which is way better than IP version 4 in terms of complexity and efficiency. IPv6 is written as a group of 8 hexadecimal numbers separated by colon (:). It can be written as 128 bits of 0s and 1s....

Difference Between IPv4 and IPv6

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 can generate 4.29×109 address space The address space of IPv6 is quite large it can produce 3.4×1038 address space 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 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 In IPv6 Encryption and Authentication are 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...
