DNS Behavior with APIM + VNet + Private DNS + Custom DNS

Summary

After introducing Private DNS zones into a VNet-integrated environment with custom DNS servers, DNS resolution behavior changes due to zone precedence and authority rules.

This can result in previously working DNS lookups failing, not because DNS is broken, but because resolution is being intercepted earlier in the lookup chain.

Local DB Configuration and Introduction

TLDR: run migrations against new db and set environment variables:

Add this from sample.env to env with accurate db names, user and passwords:

POSTGRES_HOST=localhost
POSTGRES_PORT=5432
POSTGRES_DB=sqfour

Network Gismos!

https://aka.ms/NetworkGizmos

Hello! Thank you for coming! We're going to look at three different tools for inspecting our networks!

The first tool we'll use is called nmap, you can install it for unix environments or windows. It's a command line tool for assessing serviceable ports in networks. It is also helpful for groking network subneting and cidr notation.

Let's see what we get when we query some IP address...
