Functions ¶
func AnsIsError ¶
func ConverFromBytes ¶
func ConvertToBytes ¶
func IsAddrInNetwork ¶
IsAddrInNetwork checks if an address is contained into any of the networks defined in denyNet Example: allowedNets := []string{"172.17.0.0/16"} addr := "172.17.0.2" returns true
func MsgCleanup ¶
MsgCleanup prepares the answer to be returned to the client exluding not requested records
func MsgExtractByType ¶
MsgExtractRRByType detects if an answer contains a message type. If yes returns it, else returns nil Usage:
do not filter by record name: MsgExtractRRByType(m, dns.TypeA, "") filter by record name: MsgExtractRRByType(m, dns.TypeA, "google.com")
func MsgGetMinTTL ¶
func MsgSetAuthenticated ¶
func MsgSetupEdns ¶
