  • IPB159: IPv6 Basics – Router Advertisements

    IPB159: IPv6 Basics – Router Advertisements
    Sep 5 2024
    Our series on IPv6 basics continues with Router Advertisements (RAs) within the Neighbor Discovery Protocol. We look at how hosts bootstrap onto a network using ICMPv6, discuss the timing of sending out an RA, and then cover the configuration of RAs, including key flags and options. We also talk about the importance of understanding the... Read more »

  • IPB158: “IPv6 Mostly”: A Strategy to Balance Legacy and Modern Networking Needs

    IPB158: “IPv6 Mostly”: A Strategy to Balance Legacy and Modern Networking Needs
    Aug 22 2024
    The move from IPv4 to IPv6 is not straightforward. In a world where use cases for both protocols exist, there needs to be some sort of transition. Dual stack is one option but “IPv6 mostly” is another. On today’s show, guest Ondřej Caletka from RIPE NCC explores transitioning to an IPv6-centric network while retaining IPv4... Read more »

  • IPB154: IPv6 Basics: Neighbor Discovery

    IPB154: IPv6 Basics: Neighbor Discovery
    Jun 27 2024
    Imagine a world with no broadcast storms, basically no DAD issues, not even ARP and reverse ARP. That is the world of IPv6 neighbor discovery. In today’s episode, we teach you the simplicity of IPv6 neighbor discovery: just native Layer 3 addresses, ICMPv6, and multicast. If you’ve ever been annoyed at a guy hopping on... Read more »

    IPB153: Leveraging ICMPv6 to Troubleshoot Network Issues
    Jun 13 2024
    If you don’t blame “destination unreachable” messages on DNS servers, are you even a real network engineer? All joking aside, Johannes Weber joins the show today to teach us how to use ICMPv6 to troubleshoot network issues, pinpointing if the problem is within your network or outside of it. He walks us through identifying possible... Read more »
