Security Holes in Contrast to the New Features Emerging in the Next Generation Protocol

Abstract

The next generation protocol 'Ipv6' also called Iping, which should replace the current generation of Internet protocol 'Ipv4', brings many enhancements over Ipv4. Ipv4 has been a great success for more than 20 years, since its interception in 1980 but due to limited address space, complex configuration and very important lack of security it does not fulfil the requirement of the exponentially growing internet. Because of inadequate address and for other issues, Ipv6 was proposed by the network working group of the internet engineering taskforce 'IETF' which provides many new features like quality of services, autoaddress configuration, end to end connectivity, security, simple routing header and so on. This paper identifies security holes to the new features introduced in Ipv6 and security holes that are not altered by new futures of Ipv6
