m := new(dns.Msg) m.SetQuestion("example.com", dns.TypeA)
m.Rcode = dns.RcodeServerFailureIn this example, we set the Rcode of the message to Server Failure, indicating that the server encountered an internal error. Overall, github.com/miekg/dns is a powerful Go package library for working with DNS queries and responses, and the Msg structure, along with its Rcode field, are powerful tools for developers working in this area.
