A tool that automatically updates the DNS Rewrite settings for your NextDNS account.
Originally created as a utility to be run as a scheduled task, this program was created out of my inability to configure a static local IP for my computer on my only viable network - an Android wifi hotspot. This tool solves my requirement of being able to reliably reach my pc from other devices on the network for things like Remote Desktop, Kodi and whatnot.
The solution is made feasible by the wonderful NextDNS service, and in particular their DNS Rewrite functionality that allows for setting up custom domain name resolutions that may point to a local IP.
Before running, it is required to configure the program by modifying the sections marked as 'change_this' in the code. Configurations include stuff like your NextDNS Endpoint ID, your NextDNS account credentials, and your DNS Rewrite preferences.
Additionally, this code is with quirks that meet my personal requirements - things like a check to run only if I'm connected to my home network, and a routine that returns local IP. It is recommended that you go through the code and remove functions that you don't require.
This program creates a nextDns_rewriteID.txt in the folder where it is executed, to track the DNS Rewrites it has created by their ID. Please do not modify or delete this file to ensure the program always runs successfully.
A big thanks to the developers at NextDNS for creating the friendly API used in this program, and all the people at Stackoverflow who provide insights vital to the solutions of some of my problems.
