Welcome to our special Halloween episode! Okay, not really, but we are recording in late October… This time we answer a record-breaking three questions from the same listener, Grant Taylor, who single-handedly supplied the material for all our tangents in this show. We remind everyone of the dangers of cache poisoning in a discussion about CNAMEs, we strain our memories back to the early days of DNSSEC to discuss SIG(0), and we explain and opine on EDNS Client Subnet, a recent and increasingly popular DNS protocol extension. Considering the time of year, we also lapse into a discussion of candy, specifically peanut M&Ms.
