Network Tools

Diagnose and inspect any domain, IP address, or web server in seconds with ToolSparkr's network tools. Every query runs server-side for accurate, real-world results — not cached or simulated data.

The DNS Lookup tool shows all DNS records (A, AAAA, MX, TXT, CNAME, NS) for any domain. IP Lookup reveals geolocation, ISP, and ASN information for any IPv4 or IPv6 address. WHOIS retrieves domain registration details including registrar, creation date, and expiry. Reverse IP Lookup finds all domains hosted on the same IP address.

Technical tools include HTTP Headers Lookup for inspecting response headers, HTTP/2 Checker to verify protocol support, and Brotli Checker to confirm compression is enabled. The Ping tool measures server response times from our global nodes.

Popular use cases: verifying DNS propagation after a domain transfer, checking if a CDN is serving Brotli-compressed assets, auditing HTTP security headers, finding all co-hosted domains on a shared server, checking domain registration status.
