Friends and Colleagues,


ICANN’s Office of the Chief Technology Officer (OCTO) have published a new paper entitled “Hyperlocal Root Zone Technical Analysis”.


This document provides a technical analysis of hyperlocal root service. Hyperlocal root service is an approach to make root zone content more available to resolvers by making its content local, one approach of which is described in “Running a Root Server Local to a Resolver,” RFC 8806.


This technical analysis is laid out in several sections that signify the key differences between the current root server system (RSS) and a hyperlocal root zone deployment. Each section contains a discussion on the benefits and drawbacks of those deployments.


The primary benefits of a hyperlocal root zone are that access to the root zone is more reliable and private, and responses are faster (it has lower latency).


The drawbacks of this approach are that it requires additional configuration of an already complex resolver system, which can impact root zone scalability, and reduce telemetry for the purpose of operations, analysis, and research by root server operators (RSOs) and others.


You can access the paper at https://www.icann.org/en/system/files/files/octo-027-25aug21-en.pdf.


Thank you,


Fahd Batayneh
