IPv4, the current version of the Internet Protocol deployed worldwide, has proven remarkably robust, easy to implement, and interoperable with a wide range of protocols and applications. Though substantially unchanged since it was first specified in the early 1980s, IPv4 has supported the scaling of the Internet to its current global proportions. However, the ongoing explosive growth of the Internet and Internet services has exposed deficiencies in IPv4 at the Internet's current scale and complexity. IPv6 was developed specifically to address these deficiencies, enabling further Internet growth and development, but IPv6 is also prone to routing attacks such as wormhole attack, delay attack etc.
