cloudscope

cloudscope is a Node.js library to detect whether an IP address belongs to a major cloud provider. It fetches and normalizes CIDR ranges, then lets you check IPv4 and IPv6 addresses efficiently.

---

✨ Features

• Detect if an IP belongs to a cloud provider
• Supports IPv4 and IPv6
• Providers supported: AWS, Azure, Google Cloud, Oracle, IBM, DigitalOcean, Linode, Exoscale, Vultr, Scaleway, NIFCloud
• Cached loading with configurable TTL
• Filter by provider, service, or region

---

🚀 Install

npm install cloudscope
# or
yarn add cloudscope

---

📖 Usage

const { load, isIp, getData, refresh } = require('cloudscope');

(async () => {
  // 1. Load data from providers (cached in memory)
  await load({ ttlMs: 1000 * 60 * 60 * 12 }); // cache = 12h

  // 2. Check an IP
  const result = await isIp('52.95.110.1');

  if (result.match) {
    console.log(`✅ Cloud IP detected!`);
    console.log(result);
  } else {
    console.log(`❌ Not a cloud IP`);
  }

  // 3. Restrict by provider
  const awsCheck = await isIp('52.95.110.1', { provider: 'Amazon' });
  console.log(awsCheck);

  // 4. Get dataset summary
  console.log(getData());

  // 5. Force refresh
  await refresh();
})();

⚡ API

await load(options?: LoadOptions)

Loads IP ranges from supported cloud providers into memory. Uses an in-memory cache with configurable TTL.

Options (LoadOptions):

• providers (string[]) → list of providers to load (default: all)
• ttlMs (number) → cache TTL in milliseconds (default: 6h)
• force (boolean) → ignore cache freshness and force reload

Returns:

{ loadedAt: number, count: number }

---

await isIp(ip: string, options?: IsIpOptions)

Checks whether an IPv4 or IPv6 address belongs to a known cloud provider range.

Parameters:

• ip (string) → IP address to check

• options (IsIpOptions) (optional)

  • provider → restrict to a specific provider (e.g., "Amazon", "Microsoft")
  • service → restrict to a specific service (if available)
  • regionId → restrict to a specific region identifier (e.g., "eu-west-1")

Returns (IsIpResult):

{
  match: boolean,
  reason?: 'invalid_ip' | 'provider_not_loaded',
  version?: 'ipv4' | 'ipv6',
  provider?: string,
  regionId?: string,
  region?: string|null,
  service?: string|null,
  cidr?: string
}

---

getData(): DataSummary

Returns a lightweight summary of the in-memory dataset.

Returns:

{
  loadedAt: number|null,   // when data was last loaded
  ttlMs: number,           // cache TTL
  count: number,           // number of records in memory
  providers: string[]      // list of available providers
}

---

await refresh()

Forces a reload of all provider ranges, ignoring cache.

Returns:

{ loadedAt: number, count: number }

💡 Use cases

• 🔍 Security logging: enrich logs with provider info
• 🛡️ Firewall / WAF rules: detect and allow/deny traffic from clouds
• 📊 Analytics: categorize requests by hosting provider
• 🌍 Geolocation: improve IP intelligence with cloud-awareness
