Functions ¶
func ClearDNSSEC ¶ added in v0.2.4
ClearDNSSEC returns cleared RRSIG and NSECx message
func ExchangeInternal ¶ added in v0.2.4

func ExtractAddressFromReverse ¶
ExtractAddressFromReverse turns a standard PTR reverse record name into an IP address. This works for ipv4 or ipv6.
54.119.58.176.in-addr.arpa. becomes 176.58.119.54. If the conversion fails the empty string is returned.
func HandleFailed ¶ added in v0.2.4
HandleFailed returns message specified with rcode.
func IsReverse ¶
IsReverse returns 0 is name is not in a reverse zone. Anything > 0 indicates name is in a reverse zone. The returned integer will be 1 for in-addr.arpa. (IPv4) and 2 for ip6.arpa. (IPv6).
func MinimalTTL ¶ added in v0.2.4
MinimalTTL scans the message returns the lowest TTL found taking into the response.Type of the message.
