# How to Use Oculus Proxies With Node-crawler

> Boost your crawling efficiency with Oculus Proxies in Node-crawler to distribute massive loads across thousands of residential IPs for large-scale data collection.

## What is Node-crawler?

**Node-crawler** is a specialized crawling framework that manages a request queue and concurrency. It includes built-in features like priority queuing and rate limiting. Use **Oculus Proxies** for bulk crawling, your IP will be flagged almost instantly without a proxy. This allow you to distribute that massive load across thousands of residential IPs, making the crawl appear as many individual users.

<Tip>
  If you're using **Oculus** to scrape search engines like **Google, Bing, or Yandex** and facing connection issues, your proxy type may need adjustment. **ISP Premium Proxies** provide stable and unrestricted access, preventing blocks that standard proxies may encounter. Switching to **ISP Premium Proxies** can improve performance.
