    IPB176: How to Number Point-to-Point Links
    May 29 2025
    Let’s chat about point-to-point links. On today’s episode we cover what should and shouldn’t be done, and discuss why following RFC’s doesn’t always get you to the right place. We dig into questions including: Don’t we just use link-local addresses for point-to-points? Shouldn’t we assign a /127, just like we do a /31 in IPv4?... Read more »

    IPB175: IPv6 Basics – Link-Local Addresses
    May 15 2025
    Our IPv6 Basics series continues with link-local addresses. Link-local addresses are unicast addresses used for addressing on a single link. The intent of link-local addresses is to let devices that may not have a router or global unicast address allocation mechanism still be able to communicate on a network segment. On today’s show we dig... Read more »
