IP Address Info & Classifier

Turn any IP address into structured intelligence — version, type, public/private classification, special-use range, and reverse DNS — with pure Node stdlib and zero geo APIs.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

Validation — correctly detects IPv4 vs IPv6 (rejects garbage).
Classification — public, private (RFC 1918), loopback, link-local, cgnat (RFC 6598), multicast, documentation, reserved, broadcast.
Special-use range — the exact CIDR/RFC the address belongs to (e.g. 10.0.0.0/8 Private-Use).
Reverse DNS (PTR) — automatic lookup for public addresses.
IPv4 extras — 32-bit integer and dotted-binary representation.
IPv6 extras — fully expanded form (:: un-compressed, embedded IPv4 normalized).
Bulk — pass one IP or hundreds in a single run.

Input

{
  "ips": ["8.8.8.8", "10.0.0.1", "127.0.0.1", "2001:4860:4860::8888"],
  "maxIps": 50
}

Or a single address:

{ "ip": "8.8.8.8" }

Output

One dataset item per IP:

{
  "ip": "8.8.8.8",
  "valid": true,
  "version": 4,
  "type": "public",
  "isPublic": true,
  "integer": 134744072,
  "binary": "00001000.00001000.00001000.00001000",
  "reverseDns": ["dns.google"],
  "specialUse": null
}

A private/reserved address instead returns its range:

{
  "ip": "10.0.0.1",
  "valid": true,
  "version": 4,
  "type": "private",
  "isPublic": false,
  "integer": 167772161,
  "binary": "00001010.00000000.00000000.00000001",
  "reverseDns": null,
  "specialUse": { "range": "10.0.0.0/8", "name": "Private-Use (RFC 1918)" }
}

Pricing: pay-per-result — billed once per IP classified.
