RIPE Labs has reported the initial results from an effort to measure DNS transfer size, to determine whether larger DNSSEC responses would pose problems once the K-root begins to provide DNSSEC responses to requesting resolvers, and whether the larger responses would reach the resolvers.  From the article: “The good news is that the vast majority of measurements yield transfer sizes that will fit current DNSSEC answers from root name servers,” although “some resolvers that could experience time-outs and delays due to misconfigurations and middleware.”
