Functions

func PtrNameMagic

func PtrNameMagic(name, domain string) (string, error)

PtrNameMagic implements the PTR magic.

func ReverseDomainName

func ReverseDomainName(cidr string) (string, error)

ReverseDomainName turns a CIDR block into a reversed (in-addr) name.

func TransformIP

func TransformIP(address net.IP, transforms []IpConversion) (net.IP, error)

TransformIP transforms a single ip address. If the transform results in multiple new targets, an error will be returned.

func TransformIPToList

func TransformIPToList(address net.IP, transforms []IpConversion) ([]net.IP, error)

TransformIPToList manipulates an net.IP based on a list of IpConversions. It can potentially expand one ip address into multiple addresses.

func UintToIP

func UintToIP(u uint32) net.IP

UintToIP convert a 32-bit into into a net.IP.

Types

type IpConversion

type IpConversion struct {
	Low, High net.IP
	NewBases  []net.IP
	NewIPs    []net.IP
}

IpConversion describes an IP conversion.

func DecodeTransformTable

func DecodeTransformTable(transforms string) ([]IpConversion, error)

DecodeTransformTable turns a string-encoded table into a list of conversions.
