I'm a new OpenDNS user, seeking some technical explanations.
After changing my DNS servers from my ISP's to OpenDNS, it appears every A record is resolved to 22.214.171.124.
So it appears this is a proxy solution, that "pulls" all of my outbound traffic to OpenDNS.
My question is does OpenDNS simply forward my web request to the final destination (if not blocked), w/ my true source IP (assigned by ISP) intact, or do they change the source IP to OpenDNS', like a true proxy would do?
If it's the former, then the web server would just return the response back to me directly. If my source IP is changed to OpenDNS, the web server would respond to the proxy, then back to me.
I'm asking because some websites are subscription based, especially library services, that perform authentication based on source IP.
I'd provide my source IP to the content provider, and I'm allowed to access their sites, as long as I'm coming from the source IP that I provided.
