Privacy Policy

1. Scope and Data Minimization Principle

IPAddressLookup.in is designed as a stateless networking utility. Unlike applications that require user accounts or persistent databases, our IP, RDAP, DNS, and subnet tools operate on-demand without storing personal user profiles or historical lookup logs tied to visitors.

2. How Visitor IP Addresses and Tool Queries Are Processed

• Automatic "What Is My IP" Display: When you load the homepage (/), IPv4 Checker (/ipv4-check), or IPv6 Checker (/ipv6-check), our server reads the source IP address observed by the hosting load balancer solely to return that address and its public registry/network metadata to your browser.
• Interactive Tool Queries: When you submit an IP address, ASN, or domain name to /api/ip, /api/rdap, or /api/dns, the server validates the input and queries the corresponding upstream source (Regional Internet Registry RDAP server, Cloudflare DNS-over-HTTPS resolver, or configured IP intelligence API).
• Client-Side Deterministic Calculators: Inputs entered into the Subnet Calculator, IP Range Calculator, IP Validator, and IP Format Converter are processed directly in memory and are never transmitted to third-party servers.

3. Ephemeral Rate Limiting and Operational Logs

To protect upstream registry quotas and prevent automated scraping or denial-of-service abuse, our API endpoints maintain short-lived, in-memory rate-limit counters keyed by client IP and endpoint class (with a 60-second sliding window). Standard hosting infrastructure access logs may transiently record request metadata for operational security and error diagnostics.

4. Upstream Data Processors and Public Registries

When performing live RDAP or DNS lookups, your target query parameter (for example, the queried IP prefix, ASN, or domain name—not your personal identity) is sent from our server to the authoritative Regional Internet Registry (such as APNIC, ARIN, or RIPE NCC) or public DNS-over-HTTPS resolver (Cloudflare 1.1.1.1) to fulfill the request.
