Constants

const (
    // IP4arpa is the reverse tree suffix for v4 IP addresses.
    IP4arpa = ".in-addr.arpa."

    IP6arpa = ".ip6.arpa."
)

func ExtractAddressFromReverse Uses

func ExtractAddressFromReverse(reverseName string) string

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 IsReverse Uses

func IsReverse(name string) int

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).
