    Hedge 309: DNS Persist
    Jun 19 2026
    As DNS is more widely used to distribute certificate information, proving ownership of a resource becomes more critical. The constant challenges required to prove resource ownership, however, increase delay in connecting or using a resource. DNS persists--as the name implies--creates a persistent connection between a resource and a certificate authority. Henry Birge-Lee, Michael Slaughter, and Shiloh Heurich join Russ and Tom to explain how this new record type works and it's importance to DNS.

    Hedge 306: RPKI Transport
    May 22 2026
    Synchronizing information across the Internet, at an initial glance, looks like a fairly simple problem to solve. Just copy a file to a host and create a magic protocol, right? Not really. Each kind of data has a fairly unique set of requirements--and RPKI data, used to provide security information for BGP, is no different. Job Snijders joins Tom and Russ to talk about ERIK, a protocol developed to synchronize RPKI records.
