nst tool

Overview

  • nst is a new tool written in javascript node.js. It is a generic DNS name server test tool that can be used to test new DNS features in a server.

  • A major goal is to be able to support testing of long-lived DNS connections in addition to simple query/response tests. Long-lived connections are used for DNS Privacy connection optimization, DNS Stateful Operations such as DNS Push Notifications, and service discovery with a discovery proxy and relay.

sdtest tool

Overview

  • sdtest is a client simulation tool for testing DNS subscriptions. It supports both the older Long Lived Queries (LLQ) and the new replacement DNS Push Notifications.

  • Since it is a work in progress, the best way to follow it is to look at the github sdtest project documentation that is being updated as the code is written.
