This effectively means that `doggo @2001:DB8::53 example.org` works just like we know it from `dig(1)`. This already works for IPv4 because `url.Parse` accepts a literal IPv4 address, but not a literal IPv6 address (due to parsing ambiguities with strings that look like an IPv4 address I guess). This is implemented by checking if the nameserver argument is a valid IP if the URL validation failed. If that's the case, `ns` is returned directly with the `[2001:DB8::53]:53` as address (from `net.JoinHostPort` with the default DNS port) and UDP as protocol (also the default if not specified). |
