Cloudflare Servers Share IP Addresses for Egress Traffic
Cloudflare recently detailed how it manages its servers’ egress traffic using “soft-unicast “. Soft-unicast allows multiple servers to share a single IPv4 address for their egress traffic while redirecting the response packets to the correct physical server. It provides a scalable, cost-efficient solution for Cloudflare to offer various products that require tagged egress IP addresses.
