What is the primary reason for the adoption of IPv6?
What is the primary reason for the adoption of IPv6?
- To increase the maximum datagram size
- To increase the address space and eliminate the need for NATs (correct)
- To provide improved quality of service (QoS) capabilities
- To allow for fragmentation of datagrams
What is the purpose of the 'next header' field in the IPv6 datagram format?
What is the purpose of the 'next header' field in the IPv6 datagram format?
- To indicate the presence of fragmentation
- To identify the priority of the datagram

- To specify the hop limit for the datagram
What is the benefit of tunneling in the transition from IPv4 to IPv6?
What is the benefit of tunneling in the transition from IPv4 to IPv6?
- It increases the security of IPv6 communications
- It allows IPv6 routers to communicate directly with IPv4 routers
- It eliminates the need for dual-stack routers
- It enables IPv6 datagrams to be carried as payload in IPv4 datagrams (correct)
