Thank you for your comment. I'm going through the cloudflare docs, and I have a question: why do we need to change our nameservers to Cloudflare's? I know this might sound like a noob networking question but I just can't seem to figure it out. Thanks!
No problem! You change the name servers on your registrar to cloudflare's so that when traffic goes to your.domain, cloudflare is the one that processes the dns request.
If you kept the name servers of your registrar then the traffic would just be processed by the registrar, cloudflare wouldn't even see the traffic.
Basically the name server defines your domain's current dns provider.
Hope that makes sense
Ah, this is what I'm confused about. I get that traffic would need to flow through Cloudflare's network, but why would Cloudflare require me to change my nameserver for that? How about a CNAME alias instead? What are the technical limitations for which Cloudflare asks this of me? I just want to understand the working behind them asking me to change my nameservers.
Thanks!
Setting your nameservers is simply a requirement for Cloudflare. While they theoretically could work via CNAME -- they don’t. On the other hand, their DNS is really nice and is free.
When you use their DNS, for each DNS record, you have the option to proxy traffic through Cloudflare. The proxy is what enables their CDN (and many other features such as forwarding, rewriting URLs, DDoS protection, automatic HTTPS certificates, and so on). It’s a simple on/off switch for each DNS record if you don’t want to proxy a particular host.
Thank you, that would mean that technically there is no need for cloudflare to ask one to change their default nameservers to cloudflare's nameservers - it's just that they want to run their analytics on the data transmitted in exchange for free services. I understand now. I believe some of the paid plans allow for one to use CNAMEs, which makes sense.
Thanks, now I understand. I will need to read more on the networking tech behind a Cloudflare based reverse-proxy setup (and maybe even set up my own through another VPS box someday). I'll go through the docs, thanks again!
