Overview

The ip package contains yet another IP address (and CIDR) type :-). The types differ from the ones in the net package in that they are backed by fixed-sized arrays of the appropriate size. The key advantage of using a fixed-size array is that it makes the types hashable so they can be used as map keys. In addition, they can be converted to net.IP by slicing.

Types

type Addr

type Addr interface {
	// Version returns the IP version; 4 or 6.
	Version() uint8
	// AsNetIP returns a net.IP, which is backed by/shares storage with
	// this object.
	AsNetIP() net.IP
	AsCalicoNetIP() calinet.IP
	AsCIDR() CIDR
	String() string
}

Addr represents either an IPv4 or IPv6 IP address.

func FromNetIP

func FromNetIP(netIP net.IP) Addr

func FromString

func FromString(s string) Addr

type CIDR

type CIDR interface {
	Version() uint8
	Addr() Addr
	Prefix() uint8
	String() string
	ToIPNet() net.IPNet
}

func CIDRFromCalicoNet

func CIDRFromCalicoNet(ipNet calinet.IPNet) CIDR

func CIDRFromIPNet

func CIDRFromIPNet(ipNet *net.IPNet) CIDR

func CIDRFromNetIP

func CIDRFromNetIP(netIP net.IP) CIDR

CIDRFromNetIP converts the given IP into our CIDR representation as a /32 or /128.

func MustParseCIDROrIP

func MustParseCIDROrIP(s string) CIDR

MustParseCIDROrIP parses the given IP address or CIDR, treating IP addresses as "full length" CIDRs. For example, "10.0.0.1" is treated as "10.0.0.1/32". It panics on failure.

func ParseCIDROrIP

func ParseCIDROrIP(s string) (CIDR, error)

ParseCIDROrIP parses the given IP address or CIDR, treating IP addresses as "full length" CIDRs. For example, "10.0.0.1" is treated as "10.0.0.1/32".
