Hello! I'm learning Rust and also information security, so what better way to learn than to put a tool together practicing both skills? I've tried to use a couple of different tools for subdomain enumeration (part of the Discovery-party when it comes to penetration testing), but none of them were very fast, even if the DNS resolver I pointed them towards is, so I wrote my own tool that leverages concurrency to check a lot of subdomains, fast! It's written in Rust, main parts being using Tokio and async_channels, and I think it works good enough for a first release. I wanted to get recursive…

I found out Cloudflare has a DNS over HTTPS api via 1.1.1.1 resolver, figured I'd make a small tool out of it, as somene who keeps checking domain names for side projects which I never build, this kinda helps me look for something. It's not fully accurate, because it returns unavailable even for parked pages, which technically are available, but works for me. It just checks for A records via this endpoint https://cloudflare-dns.com/dns-query?name=${domain}&type=A Just make sure to pass this header - "application/dns-json"

Hey everyone! Years ago, one of my favorite domain search tools, Lean Domain Search [1], was acquired by Automattic. Unfortunately, that's when the "enshitification" began, particularly when they started forcing the `.blog` TLD in search results. After discovering the simplicity of RDAP lookups, which can be done by fetching a JSON response directly from the client (e.g., `https://rdap.verisign.com/com/v1/domain/ycombinator.com`), I decided it was finally time to build my own solution. Here's how it works: The first tab appends prefixes and suffixes to your…
