Here’s the output of adig and ahost <https://gist.github.com/nchammas/a4c9873d8158c323796e9b47c064e63a#file-adig-ahost-txt>, both with and without the DNS servers set directly on the network interface (vs. just on the router).
I also learned that gRPC 1.60.0 may be using c-ares 1.19.1 <https://github.com/grpc/grpc/tree/v1.60.0/third_party/cares>, though again that’s just via looking at the gRPC source and not via some runtime query. > On Jan 21, 2024, at 7:34 AM, Brad House <b...@brad-house.com> wrote: > > I think homebrew distributes the 'adig' and 'ahost' utilities from c-ares. > Can you try using those to do the same lookup so we can see the results? > > On 1/19/24 11:01 AM, Nicholas Chammas wrote: >> >>> On Jan 17, 2024, at 3:38 PM, Brad House <b...@brad-house.com> >>> <mailto:b...@brad-house.com> wrote: >>> What version of c-ares is installed? >>> >> Sorry about the delay in responding.
