Probe checks whether DNS protocol is available on network on ip:port. This function do a simple query with "elmasy.com."/"A". network must be "tcp", "tcp-tls" or "udp".

func QueryA

func QueryA(name string) ([]net.IP, error)

QueryA returns net.IP structs of the answers. Returns nil in case of error. This function retries the query in case of error, up to MAX_RETRIES.

func QueryAAAA

func QueryAAAA(name string) ([]net.IP, error)

QueryAAAA returns net.IP structs of the answers. Returns nil in case of error. This function retries the query in case of error, up to MAX_RETRIES.

func QueryTXT

func QueryTXT(name string) ([]string, error)

QueryTXT returns the answer as a string slice. Returns nil in case of error. This function retries the query in case of error, up to MAX_RETRIES.

Types

type MX

type MX struct {
	Preference int    // Priority
	Exchange   string // Server's hostname
}

func QueryMX

func QueryMX(name string) ([]MX, error)

QueryMX returns MX structs of the answers. Returns nil in case of error. This function retries the query in case of error, up to MAX_RETRIES.
