Need to investigate an existing domain before buying, transferring, or troubleshooting it? Use a WHOIS lookup to review available domain registration and configuration information.
Depending on the domain and available public data, you may be able to check:
- Registrar information
- Domain status
- Nameservers
- Registration and expiration dates
- Available registration information
WHOIS lookup is particularly useful when you’re investigating a domain, preparing for a transfer, verifying domain configuration, or troubleshooting a domain-related issue.
Once your domain and DNS configuration are correct, the next step is checking whether your website and HTTPS connection are responding properly. Use these tools to identify common SSL, HTTP, redirect, and server-response issues before changing your hosting configuration.
Website & Security Tools

SSL Checker
Is your website showing an HTTPS or SSL certificate error? Use an SSL checker to verify whether the site’s certificate is valid and correctly associated with the domain.
Depending on the tool’s capabilities, you can check:
- HTTPS availability
- SSL/TLS certificate validity
- Certificate expiration
- Hostname/domain matching
- SSL/TLS configuration
An SSL check is useful when visitors see security warnings, HTTPS isn’t loading correctly, or you’ve recently installed or renewed an SSL certificate.
No Image
HTTP Status Checker
Not sure why a URL isn’t loading, redirecting unexpectedly, or returning an error? Use an HTTP status checker to see the response returned by your web server.
Common HTTP responses include:
- 200 — Request succeeded
- 301 — Permanent redirect
- 302 — Temporary redirect
- 403 — Access forbidden
- 404 — Page not found
- 500 — Internal server error
Use an HTTP status check to troubleshoot broken URLs, redirect chains, missing pages, server errors, and website availability issues.
Troubleshoot Your Website Step by Step
If your website isn't loading, your domain is pointing incorrectly, or recent DNS changes aren't working as expected, check each layer in order. This helps you identify whether the problem is with your domain, nameservers, DNS configuration, web server, or HTTPS.Check Your Domain
Confirm that the domain is registered and configured correctly.
Tool: Domain Availability Checker / WHOIS Lookup
Check Your Nameservers
Verify that your domain is using the correct nameservers, especially after a domain transfer, hosting migration, or DNS provider change.
Tool: Nameserver Checker
Check DNS Records
Inspect records such as A, AAAA, CNAME, MX, TXT, and NS to identify incorrect or missing DNS configuration.
Tool: DNS Lookup
Check DNS Propagation
If you recently changed DNS records or nameservers, check whether the updated configuration is visible through DNS resolvers.
Tool: DNS Propagation Checker
Check the HTTP Response
If DNS is working but the website still isn’t loading correctly, check whether the server returns a 200, 301, 302, 403, 404, or 500 response.

Cloudoora’s tools help you check domain availability, search domains in bulk, look up WHOIS information, inspect DNS records, verify nameservers, check DNS propagation, find IP addresses, test SSL/HTTPS, and check HTTP status codes. Use the tool that matches the domain, DNS, network, or website issue you need to investigate.
Use Cloudoora’s Domain Availability Checker to search a domain name and determine whether it is available for registration. You can check the domain before registering it for a website, business, startup, brand, or campaign.
Yes. Cloudoora’s Bulk Domain Search lets you check multiple domain names in one search instead of checking each domain individually. This is useful when comparing business names, brand domains, TLDs, startup names, campaign domains, or multiple domain options.
Use a WHOIS Lookup to investigate available registration information for an existing domain. Depending on the domain and publicly available data, you may find information such as the registrar, domain status, nameservers, and registration or expiration dates.
Use Cloudoora’s DNS Lookup to inspect the DNS records currently associated with your domain. You can check records such as A, AAAA, CNAME, MX, TXT, NS, and SRV to investigate website resolution, email configuration, and other DNS-related issues.
Run your domain through a DNS Propagation Checker after changing DNS records or nameservers. It helps you determine whether the updated configuration is visible through DNS resolvers, which is especially useful after changing hosting, moving DNS providers, updating records, or pointing a domain to a new server.
Use a Nameserver Checker to verify the nameservers currently associated with your domain. This can help confirm your DNS delegation after a domain transfer, hosting migration, nameserver change, or DNS provider switch.
Use an IP Lookup to find the IP address associated with a domain or hostname. Checking the resolved IP can help you verify where a domain is pointing and troubleshoot DNS resolution, hosting configuration, or website connectivity.
Use an HTTP Status Checker to see the HTTP response returned by your URL. Common responses include 200, 301, 302, 403, 404, and 500, helping you identify successful responses, redirects, access problems, missing pages, and server errors.
Use an SSL Checker to verify your website’s HTTPS and SSL/TLS configuration. Depending on the tool’s capabilities, you can check certificate validity, expiration, hostname matching, and whether HTTPS is available for the domain.
Start with the nameservers and DNS records, then check whether the domain resolves correctly and whether recent DNS changes have propagated. If DNS is working but the website still fails to load, check the HTTP response and SSL/HTTPS configuration.
After a hosting migration, verify that your domain nameservers, DNS records, IP address, DNS propagation, HTTP response, and SSL/HTTPS configuration are correct. Cloudoora’s domain, DNS, network, and website tools can help you check each layer before assuming the server itself is the problem.
