What?I already had a virtual machine in Azure, running SQL Server 2025 CTP 2.0 (which uses a pre-made image). I explain how to set that one up in the article Install SQL Server 2025 Demo Environment in Azure. But I wanted to use the latest preview, which is Release Candidate 0 at the time of writing.

DNS (Domain Name System) is a fundamental facilitator of several networking technologies such as mail servers, Internet browsing, and streaming services e.g., Netflix and Spotify, among others. It works on a special computer called a DNS server – which keeps a database record of several public IP addresses along with their corresponding hostnames for it to resolve or translate hostnames to IP addresses upon user request. This happens so that we would not need to bother ourselves with remembering the IP addresses of the different websites we visit. While there are several things we can discuss on DNS servers, such…
