Free Domain & Network Tools

8 powerful tools for domain analysis, network diagnostics, and online presence management — all free, instant, and no sign-up required.

Domain & Web Analysis Tools

Domainwise offers five dedicated tools for domain and website analysis. Each tool provides detailed, real-time results and connects seamlessly with every other tool in the suite.

• WHOIS Lookup — Look up domain registration details including ownership information, nameservers, expiry dates, and DNSSEC status. Powered by the RDAP protocol for reliable, up-to-date results.
• DNS Lookup — Query nine DNS record types: A, AAAA, MX, TXT, NS, SOA, CNAME, SRV, and CAA. Choose between Google and Cloudflare resolvers for DNS over HTTPS queries.
• Domain Age Checker — Find out when a domain was first registered, its age in years and days, expiry date, and registrar information. Useful for evaluating domain authority potential.
• SSL/TLS Checker — Validate SSL certificates with full details on issuer, subject, Subject Alternative Names (SANs), and days remaining until expiry. Essential for monitoring HTTPS security.
• Website Status Checker — Detect whether a website is up or down, measure response time, inspect HTTP headers, and track redirect chains. Ideal for uptime monitoring and outage diagnosis.

Network & Utility Tools

Three additional tools round out the Domainwise toolkit, covering network analysis and utility functions that complement the domain-focused tools above.

• IP Address Lookup — Look up geolocation data for any IP address, including ISP, reverse DNS, AS number, and geographic coordinates. Useful for identifying server locations and investigating network origins.
• Punycode / IDN Converter — Convert between Unicode and Punycode in both directions. Essential for working with internationalized domain names (IDNs), verifying encoding, and detecting homograph attacks.
• Social Handle Checker — Check username availability across multiple social media platforms. Secure consistent branding for your domain name and social presence before launch.

All eight tools are completely free to use, require no sign-up, and produce instant results. Whether you are a developer, domain buyer, IT administrator, or brand manager, this toolkit has you covered.

Tools for Every Role

The Domainwise toolkit supports a wide range of professional workflows. Here is how different users combine these tools for maximum impact:

• Web developers — Run a full technical audit by checking DNS records, verifying the SSL certificate, and confirming uptime and response times from a single starting point.
• Domain buyers — Perform due diligence before purchasing. Check WHOIS for ownership details, Domain Age for registration history, and DNS for existing configuration.
• IT administrators — Troubleshoot website issues by checking website status, verifying DNS records, and confirming server location.
• SEO specialists — Evaluate a domain's profile by reviewing Domain Age for authority signals, WHOIS for ownership, and SSL for security posture.
• Brand managers — Align your domain and social media presence using the Social Handle Checker alongside the domain name generator.
• International businesses — Work with non-Latin domain names using the Punycode converter to verify IDN encoding before registering.
