Given IPv6 address prefix 2001:db8::/48, what will be the last subnet that is created if the subnet prefix is changed to /52?

  • 2001:db8:0:f00::/52
  • 2001:db8:0:8000::/52
  • 2001:db8:0:f::/52
  • 2001:db8:0:f000::/52
    Answers Explanation & Hints:

    Prefix 2001:db8::/48 has 48 network bits. If we subnet to a /52, we are moving the network boundary four bits to the right and creating 16 subnets. The first subnet is 2001:db8::/52 the last subnet is 2001:db8:0:f000::/52.
