Domain Digger – Full Toolkit for Next-Level Domain Analysis
Domain Digger – Full Toolkit for Next-Level Domain Analysis
Domain Digger was born in 2021 out of my frustration with existing DNS lookup tools. I'd often find myself using multiple different tools to get the job done. What job? Understanding the technical underlying architecture of a website or app by digging into the used infrastructure. With Domain Digger I had a couple of goals: 1. A snappy user experience 2. Have all possible tools in one place and be able to quickly jump between them 3. And of course have it all open-source: https://github.com/wotschofsky/domain-digger Features include: * DNS Lookup from selectable location * WHOIS lookup * Certificate history * IP Details * A quick access bookmarklet (does anyone even remember those?) The app is built using Next.js on Vercel and shadcn/ui. Here are a couple of fun or shocking findings I gathered over the years: * GitHub uses a mixture of own IP addresses and Azure IPs depending on the region: https://digger.tools/lookup/github.com/map * Cloudflare uses different IP addresses in Europe, despite using an anycast setup: https://digger.tools/lookup/wsky.dev/map * The majority of startups use Google Workspace - Microsoft 365 is the exception * DNSSEC adoption is ridiculously low - even Google doesn't use it: https://digger.tools/lookup/google.com * Too often, companies opt not to support IPv6, even though it is easily supported by their CDN: https://digger.tools/lookup/www.deviantart.com (compare to https://digger.tools/lookup/d2ade2shja8hmk.cloudfront.net )
