Content delivery networks require strategically placed IPv4 addresses worldwide. Proper IP infrastructure ensures fast, reliable content delivery to global audiences.
CDN IP Requirements
CDNs have unique infrastructure needs.
- Global edge presence in multiple POPs
- Anycast capability for geographic routing
- High bandwidth capacity
- Clean reputation (ISPs don't throttle)
Edge Implementatiestrategie
CDN edge nodes need IPs close to end users.
Major metros in each region
IXP presence for peering efficiency
Redundant IPs per location
Anycast for CDN
Many CDNs use anycast addressing—the same IP announced from multiple locations. This automatically routes users to the nearest edge.
Anycast requires contiguous IP blocks (typically /24 or larger) and BGP capability at each location.
Streaming Considerations
Streaming services have additional requirements beyond standard CDN.
- Sustained high bandwidth capability
- Low jitter for smooth playback
- Reputation that avoids content blocks
