# Free Datacenter IPs: troubleshooting guide

Free Datacenter IPs are designed for testing and come with limits - they have a 5GB/month traffic and 20 concurrent sessions limit per user.\
​

While you can’t manually replace these IPs, we actively monitor performance and refresh IPs as needed to maintain reliability.\
Due to their shared nature, these IPs may be blocked on specific targets.\
​

For full performance and flexibility of our service, consider upgrading to a paid plan. ⬇️

Options like [Datacenter](https://oxylabs.io/products/datacenter-proxies), [Dedicated Datacenter](https://oxylabs.io/products/datacenter-proxies/dedicated-datacenter-proxies), or [Residential](https://oxylabs.io/products/residential-proxy-pools), [ISP](https://oxylabs.io/products/isp-proxies) Proxies offer greater reliability, fewer restrictions, and improved compatibility with challenging websites.
