Hi - I apologize if this is a dumb question, or if it can be done already and I just don't know how to do it.  I have checked the settings and don't see anything like this, but I don't understand all the options.


Is it possible to change a setting somewhere so that AirVPN caches DNS lookups for a longer time?  I am of course worried about my privacy and security, but doing DNS lookups as often as AirVPN does seems a bit excessive.  I seem to spend half my time waiting for lookups, especially for sites that I use a lot, even when I just accessed them a couple minutes ago.  Does AirVPN it have to do it quite so often?  Can I tell AirVPN "only do a new hostname lookup if I haven't accessed that site in 20 minutes"?


I appreciate the solid security, and I know DNS issues can be security problems, but all the waiting is really making me frustrated and I"m start to think of not using the VPN at all..  Clearly AirVPN caches the lookups *somewhere* for *some* period of time because it doesn't literally do a lookup for each instance of the domain, say, on a web page.  Is it possible to add a user-configurable option to cache for longer?  For example, I use DuckDuckGo for searches.  And I do a LOT of searches.  But if I don't access it for a few minutes, then for every search I do I have to wait for another lookup, which can take 3-6 seconds.  Doesn't sound like much, but it's annoying when you have to wait 15 times an hour.


Thanks for any tips!

That's not a feature of Eddie/OpenVPN. Your local DNS cache does it. On Windows, the cache is enabled automatically. On Linux, you need to install and configure it. To help you further: What is your OS?

Always remember:
There's a guide to AirVPN,

Amazon IPs are not dangerous here,
running TOR exits is discouraged,

using spoilers for your logs is the proper way to heaven.
Same issues are rare! Search for solutions and if not successful open your own threads.

~ Furthermore, I propose that your paranoia is to be destroyed. ~
