Introduction to IPv6 Quiz

Internet Protocol Standards

• The Internet Engineering Task Force (IETF) is responsible for defining Internet Protocol standards.

IPv4 Original Design

• Network security was given only minor consideration in the original design of IPv4.
• The technology that was not anticipated during the development of IPv4 is the massive growth of the Internet.

Internet Threats in the 1990s

• The ease of use and widespread adoption of the Internet led to Internet threats becoming prolific in the 1990s.

Objectives of IPv6

• One of the objectives after completion of the module on Introduction to IPv6 is to understand the need for IPv6.

Deficiencies of IPv4

• Network security was given minor consideration in the original design of IPv4.
• One of the deficiencies of IPv4 that IPv6 corrects is the limited address space.

Need for IPv6

• IPv6 is needed because IPv4 has a limited address space, which can only support a maximum of approximately 4.3 billion unique IP addresses.

IPv6 Improvements

• IPv6 offers improved security features and a much larger address space compared to its predecessor IPv4.
• IPv6 supports a much larger number of unique IP addresses, with a maximum of 3.4 x 10^38 possible addresses.

IPv6 Standardization

• IPv6 was fully standardized in 1998.

Relationship to IPv4

• IPv6 is considered a successor to its predecessor IPv4.
• The IETF realized in the early 1990s that IPv4's 32-bit address space was insufficient to support the growing Internet.
