Basically what the title says - Can my ISP see the exit node of my VPN ? I hope not, because that would be weird, and would defeat the whole purpose of a VPN.

A bit of backstory about why I had this question ( it is slightly long, so is totally okay for the reader to skip this part )

My partner subscribed to a McAfee security suite, that we share (because they had some promotions available or something for multiple devices). It’s not the worst thing around - the antivirus part, but it also came with their “McAfee Safe Connect VPN” service, which is infamous for having a super-invasive data logging policy. So I said fuck’em and set out for a better option.

I am more or less tech-literate, but I researched somewhat deeply‌ this time, basically to choose between “Privacy” (like Bruce Wayne - everybody knows who he is and lives in the Wayne Manor, but nobody knows what he does there, or that he has a BatCave underground), and “Anonymity” (Like Batman - everybody knows what he does - kicks ass of bad guys - but nobody really knows who he is, ok except for may be a couple of people) - basically trying to figure out if I needed a VPN at all or not.

I already have DNS-over-HTTPS enabled in all my devices - so that kinda took care of my “privacy” concerns (i.e. a nosy ISP) - although I believe my ISP can see which IP/Domain I am finally connecting to, which kinda sucks.

Apart from my ISP, the other concern was Public Wi-fi. I do work with my device(s) on-the-go a lot, which is why I have reason to ensure safety while connected to Public Wi-fi at Cafes/Restaurants/Airports. The fact that Internet is not just HTTPS - there’s telnet/FTP/SMTP/IMAP/POP3/Gopher and other protocols which have their own encryption methods (or not) also led me to the realization that DOH is not a total replacement for VPN. And the ISP can know my destination Domain even if DOH stops them from sniffing or blocking the DNS lookup itself.

In the end, I decided to go with VPN. Not any free ones (because as we all know they suck), and neither any over-promoted ones as well, like Nord or IPVanish (because they suck as well, in a different way). I chose Mullvad, but white labeled as Mozilla VPN. This is because I do use email-forwarding services to a large extent, and Mozilla is providing this combined deal of their email masking service Firefox Relay along with phone masking and VPN for 5 devices, all for a reasonable subscription (I won’t say how much because this post is not a promotion for them) - and being a long-time Firefox user (and also being anti-Google for a while), I decided to go with that (and so far all I heard about Mullvad are good things).

So far I am alright with it. Let’s see how it goes.

And that concludes my VPN journey story. While I was researching about how much my ISP can see when I connect to a VPN - I found that they can see encrypted traffic to and from my real IP, and that I connected to a “VPN server”, and nothing else.

I assume this “VPN Server” that they can see is the “entry node”, and not the “exit node” (i.e. my IP as seen by the world) - but never got a clear answer to that - which led me to my original question above.

And thanks for reading this far ! Feel free to share insights.

    You’re mostly right, if not completely right. VPN is encrypted with SSL so the ISPs only see that you exchanged information with a VPN, but not what is being exchanged.

    You may consider that maybe the ISPs can also figure out who else connects to the VPN and maybe deduce some information that way, but they can’t know everyone who uses the VPN, only those on their ISP that use it. So you can exchange information with somebody in Antarctica and the ISP has no way of knowing if it’s somebody outside or inside their ISP.

    Also, on the point of services that are not HTTPS, don’t confuse encrypted protocols with the SSL of the VPN. Your ISP will not see your unencrypted packets either of you tunnel it through your VPN. They can’t see your DNS or ping requests (assuming you are using an IP based proxy, not using a SOCKS proxy). But your VPN provider can see those unencrypted requests. So you’re choosing to trust the VPN provider with those opaque requests over your ISP.

    And last, about DNS-over-HTTP, a reverse DNS is enough for your ISP to know what domain you’re connecting to in a lot of the cases, regardless if you hide the domain name resolution. Of course, sites using shared CDNs mitigate this, but not all do.
