IPv6 Addressing & Routing

Covers Lesson 3 and Lesson 4

Checks that you can write, expand, and classify IPv6 addresses accurately, and then route between the subnets you built with them.

Topics covered

• The two shortening rules and why :: appears once
• Address types by leading bits
• SLAAC and modified EUI-64
• Dual-stack and ipv6 unicast-routing
• Global versus link-local next-hops

Every question here is answerable from the first-party notes of the lessons above. You commit to an answer before you see whether it was right.

This quiz is a Week 6 milestone in its own right. Passing it does not change the completion state of any individual lesson, and you do not need it to finish the lessons it covers.

Section quiz

IPv6 Addressing & Routing

8 questions covering Lesson 3 and Lesson 4. Answer each one before you see whether you were right.

Question 1 of 8

1. What is the shortest legal form of 2001:0DB8:0000:00AB:0000:0000:0000:1000?

2. Why may :: appear only once in an IPv6 address?

3. Which prefix is the IPv6 counterpart of RFC 1918 private addressing?

4. Using modified EUI-64, what interface ID does the MAC 00AB.CDEF.1234 produce?

5. A SLAAC host has a working global address and pings IPv6 hosts by address, but resolves no names. Why?

6. What does a SLAAC host use as its default gateway?

7. Every interface has a correct IPv6 address and is up, hosts reach their own gateway, but nothing crosses the router. What is missing?

8. Why must a link-local next-hop be paired with an exit interface?
