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

Thank you,
