Can someone explain to me why cloudflare shares IPs across customers? Why not just give one to each?

• tenebrisalietum 3y ago
  Not enough IPs, and HTTP has the "Host:" header which decouples the IP from a domain.

  That would be incredibly wasteful. It can use many IPs per host when using geographically local endpoints, and relatively few customers are large enough to need IPs to themselves.

    This is an IPv4 hack thing again, isn't it.
    • kstrauser 3y ago
      Nah, not really. It’s just TLS SNI + old-fashioned Host: headers.

  Can you explain why they wouldn't? They provide a proxying service, and we've been able to serve multiple domains on the same proxy since... The 90s?

  Do you have any idea how many customers we have?
