• increased network complexity and Internet routing expansion
• lack of end to end connectivity
• always on connections
• global boundaries

Which two options are improvements provided by IPv6 as compared to IPv4? (Choose two.)

• header supports additional fields for complex packets
• increased IP address space
• standarizes the use of NAT
• supports class based subnetting
• uses a simpler header to provide improved packet handling

Which is true of the IPv6 packet header?

• hop limit replaces the TTL field
• source and destination IPv6 addresses change while traveling from source to destination
