Question
The Internet Protocol version 4 has been a tremendous factor contributing to the growth of the Internet.
Using the Online Library, the Internet, and all course materials, research the Internet Protocol version 4 and version 6.
Describe what you believe are the important differences between IP version 4 and IP version 6.
What do you envision are the specific challenges for an organization associated with migrating from IPv4 to IPv6 and why?
What would be your criteria if you worked for a large organization and needed to make the decision to migrate to IPv6 and why?
Would dynamic addressing and private IP addresses be a factor in your decision to implement IPv6? Why or why not?
Explanation / Answer
A) Describe what you believe are the important differences between IP version 4 and IP version 6.
IPV6
IPV4
The IPv6 address fields are 128-bits. The larger address space is one reason to migrate to IPv6
The IPv6 address fields are 32-bits
The header checksum field has been eliminated because transport reliability has gone up and its overhead was unnecessary
The header checksum field in IPV4
Address resolution protocol(ARP)is replaced with a function of Neighbor discovery protocol(NDP)
Address resolution protocol(ARP)is used for mapping
To manage multicast group membership using Multicast Listener Discovery (MLD) messages
Internet Group Management Protocol (IGMP) is used to manage multicast group membership
Broad cast messages are not available. Instead a link-local is used for broadcast similar functionality
Broad cast messages are available.
Auto-configuration of addresses is available
Static or dynamic addresses is available
Inbuilt internet protocol security
Internet protocol security is optional

D)Would dynamic addressing and private IP addresses be a factor in your decision to implement IPv6? Why or why not?
Ans) Yes,dynamic addressing and private IP addresses be a factor in decision to implement IPv6.
