I would like to focus more on IPv6 on the upcoming posts and I think the best topic to start IPv6 is the discovery phase but before delving into IPv6, I need to write about how address resolution works in IPv4 world. I did read couple of RFCs as well so you may find something that you didn’t know before. I also touch on GARP and share my test results. Let’s start with the outline about what we will see on this post.

  • How does ARP work?
  • What is GARP and under what conditions we send this packet?
  • How does IPv6 neighbor discovery work?
  • We will use the following topology on these tests
