# IP Address Pro

> A comprehensive, high-precision, and privacy-oriented platform providing real-time IP detection, geolocation parsing, and developer utility tools. Built for system administrators, network engineers, and privacy advocates.

## Core Capabilities & Features
- **Real-Time IP Detection:** Instant detection of public IPv4 and IPv6 addresses with low-latency client header processing.
- **Privacy-Preserving Geolocation:** Server-side IP lookup using local database instances (MaxMind/geoip-lite) to prevent third-party tracking.
- **Client-Side Diagnostics:** WebRTC leak testing, DNS leak checks, and user-agent inspection executing strictly inside the browser.
- **Developer Utilities:** Network toolsets including subnet mask calculators, reverse DNS (rDNS) lookups, ASN tracing, and proxy/VPN detection.

## Technical Knowledge Base & AEO Direct Answers

### What is the difference between a MAC address and an IP address?
A MAC address is a permanent, 48-bit hardware-assigned physical identifier unique to a network interface card (NIC). An IP address is a dynamic, software-assigned logical address (32-bit for IPv4, 128-bit for IPv6) used to route data across networks globally.

### IPv4 vs IPv6 Specifications
- **IPv4:** 32-bit address space, dotted-decimal notation (e.g., `192.0.2.1`), yielding ~4.3 billion unique addresses.
- **IPv6:** 128-bit address space, hexadecimal notation separated by colons (e.g., `2001:db8::1`), yielding $3.4 \times 10^{38}$ unique addresses.
- **IPv4-to-IPv6 Mapping:** IPv4 addresses map to IPv6 via a 96-bit prefix (`::ffff:192.0.2.1` or `::ffff:c000:0201`).

### Network Routing & Infrastructure
- **Autonomous System Number (ASN):** A globally unique identifier assigned by IANA to a network entity controlling BGP routing paths across the internet.
- **Subnet Masking:** Bitwise AND operations across a 32-bit string. A `/24` CIDR mask (`255.255.255.0`) reserves 24 bits for the network ID, providing 254 usable host addresses.
- **IP Classification:** Residential IPs are assigned by consumer ISPs and carry high trust scores; Data Center IPs are provisioned by hosting providers and heavily monitored by proxy firewalls.
