Episode 49

Cricket and Matt took advantage of being in the same place for once to record the podcast, though that doesn’t stop us from forgetting which episode number we’re actually recording. We answer four questions on subjects relating to SPF, DNSSEC, /etc/host.conf and authoritative server selection by recursive name servers. On that last topic, Matt refers to research on server selection he contributed to and promised a link to the paper in the show notes. The paper is “Authority Server Selection of DNS Caching Resolvers” and was published in ACM SIGCOMM Computer Communication Review (CCR), April 2012.
