Subnet AnalysisConvert hex values to IPv4 or IPv6 addresses instantly. Supports bulk conversion, file upload (.txt / .csv), real-time validation, and CSV export — all processed locally in your browser.
Hex ConverterEnter any domain to run a live DNS lookup — IPv4, IPv6, reverse DNS, MX/NS/TXT records, and hosting geolocation. Real-time resolution, zero tracking, no signup required.
DNS LookupProfessional IPv6 subnet calculator with real-time validation. Calculate network ranges, subnet masks, first/last usable addresses, total addresses, and address type — with export options.
CIDR / SubnetExpand compressed IPv6 addresses to full 128-bit notation. Validate CIDR subnets, detect address types, generate reverse DNS (ARPA) records, and analyse prefix lengths instantly.
IPv6 ToolDiscover domain names and comprehensive DNS information from any IP address. Get A, AAAA, MX, NS, CNAME, TXT, SOA, PTR, and SRV records with TTL values — single or bulk.
Reverse DNSInstantly detect your public IP address with geolocation, ISP details, ASN, browser fingerprint, screen resolution, and connection type — all in real time with export options.
My IPEnter any IPv4 or IPv6 address to see the registered owner, network range, ASN, geolocation, and reverse DNS — all via live WHOIS queries with referral chain resolution.
WHOISBuilt for speed, accuracy, and privacy — everything runs live, nothing is cached.
Every lookup queries live DNS, RDAP, and WHOIS infrastructure — no stale cached databases.
Most tools process data entirely in your browser. Nothing is logged, stored, or sold.
Fully responsive design that works perfectly on phones, tablets, and desktops — no horizontal scroll.
Copy results to clipboard or download as CSV, JSON, or text for reports and audits.
No signup, no API keys, no rate limits. Use every tool as much as you need — free forever.
A, AAAA, MX, NS, TXT, CNAME, SOA, PTR, and SRV records — all in one lookup.
Every device connected to the internet — from your smartphone to a web server halfway around the world — uses an Internet Protocol address to communicate. Whether you need to check your own public IP, investigate who owns a suspicious address, resolve a domain to its hosting server, or calculate a subnet, having reliable IP tools at your fingertips is essential. Our free online IP tools give you instant access to twelve professionally built utilities that cover the full spectrum of IP address and network analysis.
Start with the IPv4 Lookup tool to find any address or your own instantly, pulling live RDAP registration data, network ownership, and reverse DNS records. The What is My IPv4 & IPv6 Address checker shows your public IP alongside geolocation, ISP, ASN, and browser fingerprint details. For security researchers and developers, Track IP by Link exposes the hosting infrastructure behind any URL, complete with interactive geolocation maps and real-time click telemetry.
Network engineers will appreciate the IPv6 CIDR Calculator and IPv6 Expander for subnet planning and address analysis, while the Class A and Class C IP Address Checkers make bulk validation of classful networks effortless. The Hexadecimal to IP Converter handles batch hex-to-IP decoding, and the Bulk DNS to IP Lookup resolves hundreds of domains in a single pass. For ownership investigations, the WhoIs by IP Lookup tool follows live WHOIS referrals from IANA through the regional registries. Every tool runs in real time, respects your privacy, and works seamlessly on any device — no signup, no API keys, no rate limits.
