    Thanks to these videos, I have gone from 0 to familiar with the first half of your text's contents in 2 days! You are an incredible teacher.

    Theres no other feeling like understanding a concept that is so unique and beautiful and elegent, it is only made possible by professors like you! Tunneling is an art

    Importance of Network Address Translation and IPv6 in Managing IPv4 Address Space
    00:13 Network Address Translation (NAT) and IPv6 address space are key to overcoming IPv4 limitations
    02:41 Network Address Translation (NAT) provides advantages such as security and flexibility.
    05:08 Network Address Translation (NAT) process and implications
    07:34 IPv6 was motivated by the need for a larger address space and introduced innovations like tunneling and flow labels.
    10:02 IPv6 header has no checksum, fragmentation, reassembly, or options fields, and allows for faster processing.
    12:36 Tunneling allows IPv6 routers to forward IP Datagrams over IPv4 networks.
    15:14 IPv4 network acts as a tunnel for IPv6 communication
    17:53 Tunneling allows co-existence of IPv4 and IPv6 for end-to-end datagram forwarding.
    20:03 Internet Protocol IP is crucial for the Internet's network layer.

    You are a great lecturer! I am baffled over and over again during the course of these lectures on how smart the solutions to lets say the IPv4 Problem is.

    Ey Jim, I just have a final exam literally of all your book, so this videos are just perfect! Please do more about the other chapters :)

    ISPs just hate giving IPv6 addresses with prefix less than /64
    I need /56 or /60 for my subrouters

    One quick Question. How does the router know that the next hop router is of type IPv4, So i need to encapsulate it into an IPv4 datagram

    • @christio02
      @christio02 Рік тому

      Probably because its both IPv6/IPv4, and knows that its connected to the next IPv6 router via a IPv4 tunnel

    • @bobjones1196
      @bobjones1196 Рік тому

      its known because of the forwarding table. The forwarding table will tell you the next hop's IP and version type.

    At 17:20, shouldnt it be B-to-C, C-to-D and D-to-E instead of B-to-C, B-to-C, B-to-C?

      has to be a typo

    • @KBrown2480
      @KBrown2480 Рік тому +1

      No, I believe it has to keep its original source address. The source of that datagram was still B (where it was created), though it wasn't its directly connected partner

    • @solomontan1524
      @solomontan1524 Рік тому

      @@KBrown2480 you misunderstand. I am not referring to the src and dest fields in the red boxes. I am referring to the lines below the three red boxes.

      Yeah it is . I think it’s a typo

      looks like a typo to me. But one discussion below added more understanding on the need to maintain source of datagram from B. This leads to another question - at E-F, why src still A, instead of D (where the IPv6 tunnel came from)?
