Functions

func IP

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

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

func IPToList

func IPToList(address net.IP, transforms []IPConversion) ([]net.IP, error)

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

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. For cases not covered by RFC2317, implement RFC4183 The host bits must all be zeros.

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.
