Building a Rust DNS Server with API: A Step-by-Step Guide to Create, Update, Delete Records, and Set Name Servers

Introduction

In this tutorial, we’ll walk through how to build a simple DNS server in Rust with a RESTful API that supports CRUD (Create, Read, Update, Delete) operations on DNS records. Additionally, we’ll cover how to set up name servers (e.g., ns1.example.com, ns2.example.com) for your DNS zones.

DNS (Domain Name System) servers are vital for translating human-readable domain names into IP addresses, enabling the internet to function smoothly. By the end of this guide, you'll have a basic DNS server capable of handling CRUD operations on DNS records and managing name servers, all via an API.

Setting Up the Rust Project

First, ensure that you have Rust installed on your machine. If not, you can install it by running:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Next, create a new Rust project:

cargo new rust-dns-server
cd rust-dns-server

We’ll use the following dependencies, so open your Cargo.toml file and add them:

[dependencies]
rocket = { version = "0.5.0-rc.1", features = ["json"] }
serde = { version =…
