DumbWhoIs Hosting Live In 5 Minutes

Deploy DumbWhoIs hosting and run a self-hosted WHOIS lookup tool where you type a domain, IP address or ASN and get ownership, geolocation and network details back in a clean page. xCloud starts the pinned image behind a Caddy gateway that asks for a username and password, because DumbWhoIs has no login of its own, and publishes it over HTTPS. It keeps no data and needs outbound internet access.

What is DumbWhoIs?

DumbWhoIs is a simple web application for looking up WHOIS, IP and ASN information using free APIs, released under GPL-3.0. Upstream lists automatic detection of the query type, direct WHOIS lookup for all TLDs, IP geolocation with fallback services, ASN details, DNS resolution for a domain's addresses, IPv6 support, dark mode, URL parameters for direct lookups and a PWA. Self-hosted DumbWhoIs is the option for people who would otherwise use public lookup websites such as whois.com.

On xCloud the template runs dumbwareio/dumbwhois build-25, pinned by digest, behind a Caddy sidecar that enforces HTTP Basic authentication on the whole site, including the lookup API. DumbWhoIs itself has no authentication. There is no database and no volume. WHOIS queries use outbound TCP port 43, and IP and ASN lookups call third-party services, so the server needs internet access.

From Sign-Up to a Live DumbWhoIs In Just 3 Easy Steps

Self-hosting a lookup tool normally means wiring up a container, an auth gateway and a TLS certificate before you can safely expose it. This is the same result without assembling any of it.

Step 01
Sign Up
Create your xCloud account and pick DumbWhoIs from the OneClick catalog. Set an Admin Username, or keep the default admin — xCloud generates a 32-character password.
Step 02
We Deploy It For You
One click. We bring up the pinned DumbWhoIs build-25 image behind a Caddy 2.10.2 Basic Auth gateway, and publish it over HTTPS on your domain.
Step 03
Start Using It
Open the HTTPS URL, enter the Basic Auth username and password from your installation credentials, and run your first domain, IP or ASN lookup.

Everything DumbWhoIs Does, On Your Own Server

DumbWhoIs runs in full here — the open-source tool is complete, and it sits behind a login gateway you control instead of a public lookup website.

Domain WHOIS Lookups
Direct WHOIS queries for any domain, with support for all TLDs including ccTLDs, from one page.
IP Geolocation And Ownership
Check IP geolocation and ownership, with automatic fallback between lookup providers if one is unavailable.
ASN Lookups
Look up ASN details for network and hosting research without leaving the tool.
Basic Auth Gateway By Default
A generated username and password gate every page and API route, so strangers can't run lookups from your server's IP.
Light And Dark Interface
A clean, responsive interface that works equally well on desktop and mobile.
Stateless By Design
Nothing is stored, so there's no database to manage and an xCloud Restart loses no data.

What You Can Do With DumbWhoIs

Check who owns a domain
Type a domain and read its WHOIS record, without visiting a public lookup site or handing it your search history.
Identify an unfamiliar IP address
Look up an address from a log file to see geolocation and the network that owns it, with several fallback services behind the scenes.
Find the network behind an ASN
Enter an AS number to see who operates it, using RIPEstat and PeeringDB data.
Share a lookup with a teammate
Use the URL query parameters and permalink anchors upstream lists to send a colleague a link to a specific result.

DumbWhoIs vs Alternatives

whois.com: If you use a public lookup site such as whois.com, DumbWhoIs is the self-hosted route: the same kind of domain, IP and ASN lookups from a page on your own domain, behind a login you control.
Domain Watchdog: Domain Watchdog has its own xCloud page and tracks domains over time. DumbWhoIs is a one-shot lookup tool that keeps no data.
Command-line whois: The whois command on a laptop gives raw text. DumbWhoIs adds a browser page that detects the query type, falls back between IP services and formats the results.
Uptime Kuma: Uptime Kuma has its own xCloud page and monitors services. DumbWhoIs looks up registration and network data on demand instead.

Hear what people are saying about us

See why agencies, developers, startups, and growing businesses choose xCloud to power their projects.

xCloud works really well, I am surprised by its performance being this the release version, I have tried many paid platforms such as runcloud, cloudpages or serveravatar, as well as free platforms such as CyberPanel, CloudPanel or Hestia Control Panel and direct competitors such as SpinupWP and FlyWP. Of all those that I have tried, the platform that works best for WordPress is SpinupWP and I believe that xCloud can reach and surpass that development, its roadmap is promising. Congratulations to the xCloud team, I hope they become the leading platform in the segment, it has all the potential to achieve it!

Brian Geovanny

I've been with runcloud for the last 3 years. However, after trying xcloud for the last month, I'm switching over. They are on a roll with their setup.

Kevin Pineda

I'm moving my servers to xCloud, a cloud control panel by M Asif Rahman and the WPDeveloper team. Their roadmap looks interesting and no, there are no team mates nor API limits with xCloud! #xCloud #wordpress #hosting

How Cloud Nine Web Elevated Client Experience While Streamlining Hosting Operations using xCloud

Ed Ellingham

xCloud is like having an expert server team on call — without the big agency costs. It's given me back my time and given my clients peace of mind. Highly recommended for freelancers and small teams who want reliable performance and security.

Dumitru Butucel

xCloud isn't just a solution. It's like one of that friend who got your back when you screw things up pretty bad.

Waqar Ahmed

Trust me when I say, once people explore the potential of xCloud they gonna switch from other panels, just keep delivering the best tech, lots of love for the team 😍😍

Rahul Singh

So far my experience has been smooth like silk. I didn't imagine that configuring and managing a VPS would be so easy. As of today, I have deployed 8 sites. The support is good, and they treat users with respect, even if they ask stupid questions (myself included). For the future, I hope for greater flexibility in scheduled backups and more comprehensive and consistent documentation. I'm sure that within a few months, xCloud will become the leader in its segment. This community is amazing, and the Staff here is super helpful.

Massimo Villa

Came from cloudways then to runcloud then to xcloud. Looks like I'm staying here.

Gerson El

I've recently taken all of my Vultr-hosted sites and gotten rid of cPanel for them to substitute it with xCloud. I have to say, I'm really impressed with xCloud so far! The interface is definitely the standout feature for me.

Tony Lewis

I came from Cloudways and won't go back. Highly impressed with xCloud. Glad I gave them a chance.

Jared McDowell

I like xCloud better than RunCloud, but one thing I'll point out is that some years ago RunCloud was hungry for business, the support was outstanding, and the community was active and helped each other. Maybe it was sold, there was a change in management, or they stopped being hungry, but the quality of the RunCloud offering declined and it hasn't been moving forward quickly. My point is that currently the xCloud team has the edge and it is theirs to keep or lose

How Kevin Heinrichs Cut Hosting Costs by 84% While Running WooCommerce & Node.js Sites Efficiently

Kevin Heinrichs

I had 150 sites on cloudways and am in the process of moving them to xcloud. Much faster and better priced.

Dan Spinoza

Dear xCloud Team, I have been using xCloud for some time now and am genuinely impressed with its capabilities and the flexibility it offers by allowing users to bring their own VPS for management. It's a fantastic service, and my experience so far has been very positive. Successful migrated 5 sites on a single server. Xcloud migration tool worked great. There were few hiccups with security plugin like MalCare but disabling the plugin prior to migration worked just fine.

Rahil Maknojia

Came from runcloud. Tried xcloud and never came back.

xCloud gave me what no other hosting platform could: the flexibility of a VPS with the convenience of managed WordPress. As a solo founder running an entire business on one server, that combination is an important unfair advantage.

Frequently Asked Questions

Feel free to contact us with any questions or concerns you may have.

What is DumbWhoIs used for?

DumbWhoIs is used to look things up. You enter a domain name, an IP address or an ASN, and it works out which you gave and returns WHOIS data, geolocation and network ownership details, with the source of each result noted. It suits admins who check domains and addresses often.

Is DumbWhoIs free and open source?

Yes. DumbWhoIs is open source under GPL-3.0, so the tool has no licence fee. The xCloud charge is the Cloud VPS plus the deployment. The third-party lookup services it calls are free APIs with their own limits and terms.

Can you self-host DumbWhoIs with Docker?

Yes. For DumbWhoIs Docker hosting the template runs the upstream dumbwareio/dumbwhois build-25 image, pinned by digest, behind a Caddy Basic Auth gateway with HTTPS on your domain. It declares no volume and needs no setup beyond choosing the gateway username, because the generated password appears on your credentials card.

How much RAM does DumbWhoIs need?

DumbWhoIs's manifest floor is 256 MB of RAM, one core and 1 GB of disk, since it is a single Node.js process with no database. Upstream publishes no sizing figures, so these are conservative values. The 6 GB plan sold here is many times what the tool needs.

Does DumbWhoIs have its own login?

No. Upstream lists no authentication required. The template therefore adds a Caddy gateway with HTTP Basic authentication in front of the whole site, including the lookup API, so strangers cannot run lookups from your server's address. The gateway is xCloud's addition rather than an upstream feature.

What network access does DumbWhoIs need?

Outbound internet access. WHOIS queries use TCP port 43 to registry servers, IP lookups call third-party APIs, one of them over plain HTTP, and ASN lookups use RIPEstat and PeeringDB. The app does not work offline or on a host that restricts outbound traffic, so check egress rules before relying on it.

Which services does DumbWhoIs query?

Per the template README, WHOIS queries go straight to registry servers, IP lookups use ipapi.co, ipwho.is and ip-api.com with fallbacks, and ASN lookups use RIPEstat and PeeringDB. Your lookups therefore leave your server for those third parties, so avoid it for queries you consider sensitive.

Does DumbWhoIs store any data or need backups?

No. The template is stateless and declares no volume, so there is no application data to restore. Lookups are not saved, and the gateway credentials live in the Environment editor. Server backups from xCloud still cover the machine itself if you run other apps beside it.

Backups in xCloud

How do I upgrade DumbWhoIs?

Upstream publishes only build-number tags, and the template pins build-25 by digest, so a catalog change leaves a running install alone. To move on, review the newer build's changes, then select a later template version that pins its digest. Existing installs stay on their image until then.

How do I change the gateway password?

Edit ADMIN_USERNAME or ADMIN_PASSWORD in the Environment editor and choose Save & Redeploy; they are applied on every start. You can also set SITE_TITLE for the page heading. If you set ALLOWED_ORIGINS, include your exact public https origin or requests get a 403.

Can I run DumbWhoIs in the cloud on xCloud?

Yes. DumbWhoIs cloud use puts the tool and its Caddy gateway on a dedicated Cloud VPS, with your domain and certificate attached; it is usually ready within a minute. Another provider's server can be enrolled as self-managed, provided it allows outbound connections for lookups.

Can I cancel anytime?

Yes. There is no lock-in — cancel any time. Hosting is billed monthly and charged for what you actually use, so when you delete the server the unused balance is refunded to your account, less up to 10% in payment-processing fees.
