摘要：This article looks a few steps beyond the Root Scaling Study report from 2009. [1] In 2009, the Internet Corporation for Assigned Names and Numbers (ICANN) board commissioned a report to evaluate the effect of scaling the root zone from its current size to an undefined but larger root zone. Attributes considered were Domain Name System Security Extensions (DNSSEC), Internet Protocol Version 6 (IPv6), Internationalized Domain Names (IDNs), and a larger number of entries in the zone. The report itself focused on the editorial processes and presentation of the finished root zone to the greater Internet. The report concluded that with prudence and with the addition of some "watch & warn" systems in place, the root zone could accommodate adding IPv6, DNSSEC, and IDNs along with other new Top-Level Domain (TLD) entries in a controlled manner. What the report did not consider was the effects of the deployed Internet infrastructure on the ability to get this new information into the rest of the Domain Name System, (DNS) infrastructures of the Internet. Early experimental evidence [7, 8] suggests that the current state of infrastructure deployment will create problems for the deployment of these attributes.
