I would say "I'm happy to answer questions" but I'm not sure what I could answer; for a while now, I frankly forget that I have it even installed. It pretty much Just Works.
Warp is a set of apps that will set your phone (and with this, today, your computer) to use 188.8.131.52 for resolving your DNS. But additionally, it uses the Wireguard protocol to connect, which is a VPN protocol. This hides the contents of your connection from your ISP or network provider. It does mean you're connecting to Cloudflare, and so we've made a bunch of privacy commitments, and gotten external auditing to back those up: https://news.ycombinator.com/item?id=22747770
The above is all free. You can pay a small subscription fee to get access to Warp+, which uses Cloudflare's "Argo" product to route your requests faster.
Does that make more sense?
My understanding of that blog post is:
* 184.108.40.206 is Cloudflare's DNS resolver.
* Warp is a free VPN service, using the Wireguard protocol, with the exit at your nearest Cloudflare data center.
* Warp+ is a $5/mo. paid tier of the VPN service, with the exit at the Cloudflare data center nearest your destination, which ought to be faster.
* All of these are enabled on mobile via the app called "220.127.116.11".
I don't think "Warp is a set of apps that will set your phone to use 18.104.22.168 for resolving your DNS" is right -- but I could be misunderstanding either the product or Steve's summary ...
Warp is a vpn service, but I hesitate to just say "yes" in this case because of the caveats around end-users seeing your IP. Many folks use vpns to attempt to hide information from the site that they use, but this doesn't inherently do that, it hides the information from your internet provider. When this was announced on HN, there was a lot of arguing about that, so I tried to sidestep it by just saying plainly what it does.
If I'm trading one centralized service for another, there is no net gain.
(if the address you are trying to go to is hosted by Cloudflare, they route it using your normal connection so that it'll be quicker than going an additional couple hops to the WARP server and then to the Cloudflare dc nearest to the WARP server. you could say that this kills the privacy argument, but using their VPN at all means they can see what sites you are going to, so you'd already be trusting that they don't log.)
And fwiw, since I'm sure someone will think it - I don't want to manage my own VPN on some remote server. Not only would I put myself at risk because I don't have the experience to manage a secure server of such importance, but all I did was move my risk from my ISP to some other endpoint (VPS hosting/etc).
It feels like a game of risks no matter what you do.
