You could now test that hypothesis (if you dont exactly trust your reliable sources ;-)
dig @mtndnsserver www.google.ug and dig @8.8.8.8 www.google.ug The first one should fail, the second one should succeed. > > Hello, > > Thanks for the sense of direction offered. I have been reliably informed that the problem is originating from MTN our ISP that have issues with resolving .ug domain extensions and since google.com is redirected to .ug DNS that is why I was unable to access gmail, and google.com. but the ISP is trying to manage his side to sort out .ug resolution issues. Hope this is not to me only. In fact from my DNS it can resolve google.com and I can ping it. But when I type google.com/gmail.com they are redirected to google.co.ug for which .ug has issues. > > Thanks > > From: [email protected] > To: [email protected] > Date: Mon, 31 Oct 2011 12:00:21 +0300 > Subject: Re: [LUG] DNS Resolution > > > > > > > > I find the magical dig command quite useful for this. > > > dig @yourserver www.google.com > > > will show you how your server is resolving www.googl.com > > > Sometimes there is an authorive section in the result that will show you how the server came up with the results its presenting you.
