I am porting a project from the now deprecated dns_util api to use the DNS Service Discovery api.

With dns_util I am able to specify a DNS name server to use for resolving queries. This is useful for testing new servers or propogation when changes have been made to DNS records.

Is it possible to specify the nameserver to use with DNS Service Discovery?

You’re referring to the DNS-SD API, right? So the thing you get when you include <dns_sd.h>?

If so, the answer is “No.” That API always uses the standard system resolver configuration [1].

[1] Note that I said “resolver configuration” here, not simply “resolver”. The exact resolver it talks to depends on a lot of different factors.

Thanks Quinn. I suspected that to be the case but great to have it confirmed.
