Functions

func FilterFirstRR

func FilterFirstRR(rrs []dns.RR, rrType uint16) dns.RR

Useful function to return the first occurence of a resource record of a specific type. This method is faster than filterRRs when we are interested in only one record (like SOA)

func FilterRRs

func FilterRRs(rrs []dns.RR, rrType uint16) []dns.RR

Useful function to retrieve all records of a specific type from the DNS response message. We assume that the resource record is an instance of the specific type based on the Rrtype attribute
