When you enter any website URL or domain, we show you:
Hosting Provider name (e.g. Hostinger)
Server IP address
Online/Offline status
Geolocation (city & country of the server)
Nameservers in use
Quick link to WHOIS domain registration info
Share buttons for social networks
We query multiple DNS and HTTP header sources (including RDAP and IP-to-ASN lookups) to pinpoint the company that owns or resells the IP block. Accuracy is typically > 95%, and we update our IP database monthly to stay current.
Not yet—but bulk lookup is on our roadmap. Meanwhile, you can run sequential lookups, or copy the resulting share link to distribute each result easily.
We refresh our geolocation data every 4 weeks. This ensures that new data centers and IP re-allocations are reflected promptly in your results.
Up/Online: The server responded to our TCP ping and HTTP requests within a 5 second timeout.
Down/Offline: No response or timed out.
This gives you a real-time snapshot of the site’s reachability.
No. All lookups are stateless and ephemeral—no history is kept or published under your IP or email. The only data you control is what you share manually via the social buttons.
Nameservers (NS records) indicate where DNS records for the domain are managed. If you see vs1.registrar-dns.com, that’s typically the registrar’s default—the tool flags it in case you need to point it to your host’s DNS.
We provide a “Check WHOIS” shortcut that opens the domain’s public WHOIS lookup in a new tab. For privacy reasons, we don’t mirror all WHOIS details, but you’ll get full registration, registrar, and contact status there.
Troubleshooting latency: Ensures you pick a host closer to your audience.
Security audits: Helps identify CDN, DDoS protection, or firewall layers.
Competitor analysis: See what infrastructure similar sites use.
Due diligence: Validate any host’s claims before signing up.
Use the built-in share icons (LinkedIn, Facebook, WhatsApp, Reddit) to post a direct snapshot link of your lookup. Colleagues can click that link to see exactly the same details you did—no extra steps required.
A web hosting provider stores your site’s files on internet-connected servers, while WHOIS information reveals domain registration details such as owner, registrar, and expiration date. A hosting checker tool (or “Who Is Hosting?” tool) lets you identify which company powers a site’s hosting by inspecting DNS and server headers. Although hosting and domain registration are related, they serve different roles: hosting makes a site accessible online, whereas domain registries govern domain name assignments. By leveraging a hosting checker, you can compare plans, validate providers’ claims, and even test services before purchase. Vetting a host’s infrastructure, support, and performance is critical, and keeping WHOIS data private helps protect privacy and reduce spam. Below, each question is addressed in depth, using concise language and actionable insights.
A web hosting provider is a company that allocates space, resources, and connectivity on its servers so individuals and organizations can publish websites and applications on the Internet. They manage physical or virtual machines in data centers, ensuring constant power, cooling, and network access—elements you’d otherwise need to handle yourself. Most hosts bundle additional services such as control panels, email accounts, and one-click installers for popular software like WordPress. Providers often differentiate themselves by the level of performance (SSD vs. HDD, CPU/RAM quotas), security features (firewalls, DDoS mitigation), and support options (live chat, 24/7 ticketing) they include in each plan.
WHOIS is a standardized protocol that returns registration details of a domain name, including the registrant’s name, contact information, registrar, registration date, and expiration date. This data helps verify domain ownership, troubleshoot DNS issues, and check whether a domain is available or already taken. Key fields include:
Registrant: The individual or organization that holds the domain rights.
Registrar: The accredited company where the domain is registered.
Nameservers: DNS servers responsible for directing traffic to the hosting provider.
Creation & Expiry Dates: Indicate when the domain was first registered and when it must be renewed.
To identify the underlying hosting company, a hosting checker tool inspects a website’s DNS records and server response headers. By entering any URL, you can:
Reveal the hosting provider powering the site (e.g., AWS, GoDaddy, SiteGround).
Compare performance metrics such as response time and SSL configuration.
Detect content delivery networks (CDNs) or reverse proxies that may cache content globally.
Validate provider claims before purchase, ensuring advertised features like WordPress-optimized servers are genuine.
This tool accelerates due diligence, letting you make data-driven decisions about which host best meets your performance and budget requirements.
Website hosting and domain name registration serve complementary but distinct roles.
Hosting: Involves renting server space, bandwidth, and computing resources to store and serve your website’s files and applications.
Domain registration: Grants you the right to use a particular domain name (e.g., example.com) by registering it with an ICANN-accredited registrar; it does not include server space.
In practice, you must link your domain (via DNS A or CNAME records) to the IP address provided by your host. You can use separate companies for each service—register a domain at Namecheap and host with HostGator, or get both from one provider for added convenience.
Using a hosting checker streamlines the purchase process by helping you:
Identify real-world examples: See which hosts power top-performing sites in your niche.
Filter by geography: Lookup sites hosted close to your target audience to minimize latency.
Assess tech stack: Check if the provider supports required technologies (PHP version, Node.js, Docker) via server headers.
Validate SSL and CDN: Ensure they offer HTTPS and global caching features critical for speed and security.
After gathering this data, go to your chosen host’s website, select a plan matching your needs, and register your domain or update DNS settings accordingly.
When vetting hosts, focus on these criteria:
Uptime Guarantee & SLA: Look for at least 99.9% guaranteed uptime, with financial compensation for downtime.
Performance Benchmarks: Review independent speed tests to compare response times under load.
Customer Support: Prioritize 24/7 support with multiple channels (chat, phone, email) and documented response times.
Scalability Options: Ensure you can upgrade from shared to VPS or cloud hosting without downtime.
Security & Backups: Verify free SSL, daily backups, malware scanning, and DDoS protection are included.
User Reviews & Reputation: Check forums and review sites for honest customer feedback on reliability and support responsiveness.
Yes, most registrars offer WHOIS privacy protection (also called domain privacy) for a nominal fee. This service replaces your personal contact details in the public WHOIS directory with the registrar’s proxy information, shielding you from spammers and identity theft attempts.
Organizations often mask their WHOIS details to:
Protect personal data: Avoid exposing email addresses and phone numbers to harvesters.
Prevent spam: Public WHOIS entries are a prime source for bulk email lists.
Enhance security: Obscuring ownership details makes it harder for malicious actors to target executives or perform social engineering.
Maintain brand confidentiality: Pre-launch projects or acquisitions can remain undisclosed if domain ownership isn’t publicly linked.
By combining these strategies—robust hosting, informed due diligence, and prudent privacy practices—you’ll ensure a secure, high-performance web presence that stands out in search and provides an excellent user experience.
