It works fine > (i.e. it uses UDP by default, and TCP when asked to) for me. Yes, I worked out it was boilerplate for the general condition. A = cosmetic nit that makes me do a double-take on my first usage strikes me as=20 rough around the edges. YMMV. drill certainly looks like a drop-in=20 replacement for the common case as you suggest. But if it's not called 'dig' and I've never heard of 'drill', I'm unlikely to reach for = 'drill', hence the alias suggestion. I *had* never heard of 'drill' until this thread came up. > FWIW, the reply I got was not truncated.

I have detected there is some kind of stealth DNS interception at work in the past, although I think it's more central than the CPE. Mark=
