DNS Lookup for Raycast

Check DNS propagation instantly using the world's fastest resolvers and physical probes.


DNS Lookup for Raycast is a powerful, zero-config tool designed for developers and sysadmins. It offers two modes: a Fast Check for immediate debugging via DoH (DNS over HTTPS) or classic DNS (UDP port 53), and a Global Check to verify worldwide propagation using physical probes via the Globalping network.

🚀 Features

⚡️ Fast Check (Instant)

Query the 4 major DNS providers simultaneously, plus the resolver configured on your machine. Perfect for checking if your changes are live.

  • 🇺🇸 Google Public DNS (8.8.8.8)
  • ☁️ Cloudflare (1.1.1.1)
  • 🇩🇪 DNS.SB (Europe)
  • 🇨🇳 Alibaba DNS (Asia)
  • 💻 System DNS (your local or corporate resolver, always queried over classic DNS)

Each result shows the transport that answered it: 🔒 for DoH, 🔓 for classic DNS. By default, the extension uses DoH and automatically falls back to classic DNS (UDP port 53) when HTTPS lookups are blocked, for example behind a firewall that only allows port 53.

Some networks intercept port 53 and answer every classic DNS query themselves. In that case, classic DNS (🔓) results come from that network resolver rather than from the provider shown on the row.

🌍 Global Check (Propagation)

Verify your DNS propagation across the globe using real physical probes (not just proxies).

  • Surgical Precision: Queries 8 probes strategically distributed across North America, Europe, Asia, South America, and Oceania.
  • Real-world data: Shows the country flag, and the ISP/network name (e.g., Comcast, Orange, AWS) in the detail panel.
  • Zero-Config: Works out-of-the-box without an API key (uses the free tier limits).

🛠 Supported Records

  • Standard: A, AAAA, CNAME, MX, NS, TXT.
  • Advanced: SOA (formatted for readability) and SRV.

⚙️ Configuration (Optional)

The extension works perfectly without any configuration. Two optional preferences are available in the Raycast extension preferences:

PreferenceDescription
Fast Check TransportAuto (DoH, Fallback to UDP 53) (default), DNS over HTTPS Only or Classic DNS Only (UDP 53). Pick the UDP option when your network forbids encrypted DNS.
Globalping API KeyBypass the anonymous rate limits and use purchased Globalping credits if needed.

To get a Globalping API Key:

  1. Create an account on Globalping.
  2. Generate an API Token.
  3. Enter it in the Raycast extension preferences.

Fast Check Fast Check: the 4 public resolvers and your system DNS, with the transport used (🔒 DoH, 🔓 classic DNS) and whether their answers agree.

Fast Check detail panel Detail panel (Cmd + D): every record, with the server, transport and status.

Global Check Global Check: worldwide propagation from 8 Globalping probes.

Global Check detail panel Probe details: location, network, resolver and every record.

💡 How to use

  1. Enter a domain (e.g., google.com) in the command argument, or in the search bar and press Enter.
  2. Fast Check runs automatically when the domain is passed as an argument.
  3. Select a Record Type (A, MX, TXT...) via the dropdown: the current check runs again with it.
  4. Press Cmd + Shift + Enter (Ctrl + Shift + Enter on Windows) to switch to Global Check.
  5. Press Enter on a result to copy its records.
  6. Press Cmd + D (Ctrl + D on Windows) to show the detail panel with every record and the resolver or probe information.

The section header tells you whether all resolvers or probes return the same answer (All identical or Answers differ), which is what you want to see once a change has propagated. Domains using geo-routing (CDNs, large websites) legitimately return different answers.

🛡 Privacy

This extension communicates directly with:

  • dns.google / 8.8.8.8
  • cloudflare-dns.com / 1.1.1.1
  • doh.dns.sb / 185.222.222.222
  • dns.alidns.com / 223.5.5.5
  • the DNS resolver configured on your system
  • api.globalping.io

Provider logos are loaded through Raycast's favicon service. No data is sent to any other third-party server or analytics.

This extension uses the awesome services of Globalping and standard DoH providers. I am not affiliated with, partnered with, or compensated by any of these companies — I simply use their free services to make sysadmins' lives easier.
