Resource records are native types. They are not stored in wire format. Basic
usage pattern for creating a new resource record:
r := new(dns.MX)
r.Hdr = dns.RR_Header{Name: "miek.nl.", Rrtype: dns.TypeMX, Class: dns.ClassINET, Ttl: 3600}
r.Preference = 10
r.Mx = "mx.miek.nl."
r := new(dns.MX)
r.Hdr = dns.RR_Header{Name: "miek.nl.", Rrtype: dns.TypeMX, Class: dns.ClassINET, Ttl: 3600}
r.Preference = 10
r.Mx = "mx.miek.nl."
Or directly from a string:
mx, err := dns.NewRR("miek.nl. 3600 IN MX 10 mx.miek.nl.")
mx, err := dns.NewRR("miek.nl. 3600 IN MX 10 mx.miek.nl.")
Or when the default origin (.) and TTL (3600) and class (IN) suit you:
mx, err := dns.NewRR("miek.nl MX 10 mx.miek.nl")
mx, err := dns.NewRR("miek.nl MX 10 mx.miek.nl")
Or even:
mx, err := dns.NewRR("$ORIGIN nl.\nmiek 1H IN MX 10 mx.miek")
mx, err := dns.NewRR("$ORIGIN nl.\nmiek 1H IN MX 10 mx.miek")
In the DNS messages are exchanged, these messages contain resource records
(sets). Use pattern for creating a message:

m.SetQuestion("miek.nl.", dns.TypeMX)
