Preventing specific IP addresses or CIDR ranges from accessing your redirect links. Used to block fraudulent clicks, competitor spying, and known bot networks.
IP blocking is the most direct form of click fraud prevention. When you identify an IP address or range that's generating fake clicks, you add it to a block list. Any future clicks from that IP are intercepted before they reach the destination URL, preventing wasted ad spend and inflated analytics.
| Type | Example | Use Case |
|---|---|---|
| Individual IP | 192.168.1.100 | Block a specific bad actor |
| CIDR range | 192.168.1.0/24 | Block a subnet (256 IPs) |
| Global block | Applies to all your links | Known bot networks, data centers |
| Per-link block | Applies to one specific link | Campaign-specific fraud source |
| Temporary block | Expires after set duration | Suspicious activity that may be temporary |
GeoRedir supports individual IP, CIDR range, global, per-link, and temporary blocks. Blocked IPs are checked at the edge (Cloudflare Workers) with KV-cached lookups for sub-millisecond performance. The traffic quality dashboard surfaces suspicious IPs automatically. Manage blocks from the dashboard or via API. See the Click Fraud Protection Guide for setup.
GeoRedir checks blocked IPs in under 1ms at Cloudflare's edge. Global, per-link, and temporary blocks.
