CloudFlare hosts reddit, is that correct?

  You're right!

  Yes. The NS records list reddit nameservers (usually you need to use CF nameservers for using their service, using your own nameservers require more config) but the A records list CF IPs (free users just get two IPs, reddit has quite a lot) reddit.com. 22 IN A 198.41.209.143 reddit.com. 22 IN A 198.41.208.141 reddit.com. 22 IN A 198.41.209.137 reddit.com. 22 IN A 198.41.208.139 reddit.com. 22 IN A 198.41.208.143 reddit.com. 22 IN A 198.41.208.142 reddit.com. 22 IN A 198.41.209.139 reddit.com. 22 IN A 198.41.209.141 reddit.com. 22 IN A 198.41.209.138 reddit.com. 22 IN A 198.41.209.140 reddit.com. 22 IN A 198.41.208.138 reddit.com. 22 IN A 198.41.208.137 reddit.com. 22 IN A 198.41.209.142 reddit.com. 22 IN A 198.41.208.140 reddit.com. 22 IN A 198.41.209.136

    So is that like load-balancing out from reddit.com to all those IPs, is that the purpose of so many?
  • breakingcups 11y ago
    Huh, interesting. I didn't even know they'd allow you to do that. I assumed CF requires full DNS control to allow quickly switching over IP's in case of DOS and such.
    • zuck9 11y ago
      HN does it via CNAMEs (this doesn't require manual editing of the IPs and CF can do it when they need to): news.ycombinator.com. 76 IN CNAME news.ycombinator.com.cdn.cloudflare.net. news.ycombinator.com.cdn.cloudflare.net. 124 IN A 198.41.191.47 news.ycombinator.com.cdn.cloudflare.net. 124 IN A 198.41.190.47

  They reverse-proxy reddit (and hacker news) - but they don't actually host the website (i.e. the application, databases, etc).
  • humanarity 12y ago
    Does that mean when I make a request to reddit or HN, CF fetches the data and I get it through their proxy? Or am I missing something ...
    • btian 12y ago
      Yes.
      • philip1209 12y ago
        And to tack on - this is how they act like a CDN. In general they don't pull CSS, images, etc every time from your server - they pull it once, then cache it at edge locations.
        • humanarity 12y ago
          Got it, cool.

            They also capture all your content and communications.
            • bigiain 12y ago
              More specifically - they terminate your SSL connections, thereby having the cleartext of your traffic - and doing whatever their NSL/gag-order requires them too do before fetching/forwarding your request to the appropriate chache/endpoint.

  To clarify terminology -- CloudFlares does not host websites. They provide DNS service and performance/security services.
  • humanarity 12y ago
    Right ok.
