Not sure about this. I've tried to use OpenDNS behind a "buy my wireless for 24 hours" at an airport and I still got the page requesting me to buy a page.
Also, even when I pinged servers the IPs were resolving to their "purchase" page. Unfortunately, I didn't have an IP of a site on hand to see if I could request by IP out.

- barrkel 18y agoIf the captive portal is rerouting every IP packet (apart from DNS lookups) from an unauthorized MAC to the same central server (so that it can spoof the HTTP redirect to the payment page), this is exactly what you'd expect to see. It doesn't matter what DNS you're using - the DNS lookups should resolve to correct IPs otherwise your local DNS cache would be poisoned.
