Question
You have an Azure Virtual Network named VNet1 that has IP address spaces assigned to 192.168.0.0/16 and fd00::/48.
On VNet1, you plan to create a subnet named Subnet1.
You need to ensure that Subnet1 has the largest available IPv6 address space.
Which IPv6 prefix length should you use?
A. /16
B. /32
C. /48
D. /64
Answer
D. /64
Explanation
The subnets for IPv6 must be exactly /64 in size. This ensures future compatibility should you decide to enable routing of the subnet to an on-premises network, since some routers can only accept /64 IPv6 routes. If you try to use any other prefix size when specifying the Subnet1 IPv6 address space, you will get the following error: “Prefix length can only be 64 in the case of IPv6 address spaces in subnets.”
