Dear Brian


+trace makes it to do query locally. There's inbuild DNS recursor within
the tool. When you run with +trace, @8.8.8.8 is pretty much ignored.



Try running:

dig +trace whoami.akamai.net. @8.8.8.8


You will get your own IP. So query is resolving for .bd domain but from
your local UK based reply.



Thanks.
