About VSPIC
Free IP, DNS, SSL, and network diagnostics — built for IT teams, developers, and learners.
VSPIC is a free toolkit for IP addresses, DNS records, SSL certificates, email authentication, and network diagnostics — runnable in your browser without installing Wireshark or paying for enterprise SaaS seats.
We built it for sysadmins triaging propagation issues, developers debugging SPF/DKIM on staging domains, students learning how traceroute works, and privacy-minded users who want WHOIS and IP lookup without opaque third-party data retention policies. Each tool documents what it queries, what it returns, and what it does not store.
The library spans IP geolocation hints, DNS lookup and propagation checks, port scanning for authorized targets, SSL expiry monitoring, HTTP header inspection, and dozens of reference utilities (CIDR, MAC OUI, JWT decode, robots.txt builder). Guides and blog posts explain concepts — IPv4 vs IPv6, DNS vs WHOIS, VPN vs proxy — in plain language with links back to live tools.
VSPIC is part of VSPic.com alongside image, PDF, and AI utilities. We ship improvements weekly based on search demand and support tickets. No signup is required for core lookups; paste a hostname, run the check, copy results into your ticket or runbook.

Frequently Asked Questions
VSPIC is a free collection of IP, DNS, SSL, and network diagnostic tools at vspic.com/ip-tools — built for IT staff, developers, students, and anyone troubleshooting connectivity or domain configuration.
Yes. Core tools run free in your browser. Some lookups query public APIs or DNS resolvers on your behalf — we do not sell your query history or require an account for standard checks.
We design tools to minimize retention. Server-side lookups process your input to fetch results — see our privacy policy for details. Prefer client-side tools when you need purely local processing.
Only scan systems you own or have written permission to test. Unauthorized port scanning may violate policy or law — our UI reminds you to stay within authorized scopes.
VSPIC bundles 100+ utilities with consistent UX, guides, and cross-links on one domain — image and PDF tools included when your workflow needs more than DNS.
