Internet - Protocol
Internet : “Network of Network”
&
Protocol : “Set of rules that used to controlling something.”
So….IP defines as the principal communication protocol used for relaying network packets across internet using IP suit.
Versions of Internet-Protocol
Ipv-4
The first major version of IP was IPv4 (Internet protocol version 4), is the dominant protocol of the internet.
Ipv-4 developed in 1978.
Total of 4 billion IP addresses available in Ipv-4.
Ipv-6
IPV6 design started in 1993 when IETF forecasts showed
IPv4 depletion between 2010 and 2017
Completed, tested, and available for production since 1999
Total of
340,282,366,920,938,463,463,374,607,431,768,211,456
approx. 6.5 billon IP addresses available
Features of Ipv-6
1. New header format
2. Large address space
3. Efficient and hierarchical addressing & routing
4. Stateless and stateful address Configuration
5. Built-in security
6. Better support for OS
7. New protocol for neighboring node interaction
8. Extensibility
Security
The protocol for IP encryption and authentication, forms an integral part of the base protocol suite in IPv6.
IP packet header support is necessary in IPv6,this is unlike IPv4,where it is optional.
Built-in in IPv6, unlike is built-on in IPv4.
Conclusion
IPv6 is NEW …
built on the experiences learned from IPv4
new features
large address space
new efficient header
auto configuration
… and OLD
still IP
build on a solid base
started in 1995, a lot of implementations and tests done
