Functions

func Cmp

func Cmp(a, b net.IP) int

Cmp compares two IPs, returning the usual ordering: a < b : -1 a == b : 0 a > b : 1

func FirstIPInSubnet

func FirstIPInSubnet(addr *net.IPNet) (net.IP, error)

FirstIPInSubnet gets the first IP in a subnet

func GenerateNetworkFilters

func GenerateNetworkFilters(f map[string][]string) ([]types.FilterFunc, error)

func GenerateNetworkPruneFilters

func GenerateNetworkPruneFilters(f map[string][]string) ([]types.FilterFunc, error)

func IsIPv4

func IsIPv4(netIP net.IP) bool

IsIPv4 returns true if netIP is IPv4.

func IsIPv6

func IsIPv6(netIP net.IP) bool

IsIPv6 returns true if netIP is IPv6.

func LastIPInSubnet

func LastIPInSubnet(addr *net.IPNet) (net.IP, error)

LastIPInSubnet gets the last IP in a subnet

func NextIP

func NextIP(ip net.IP) net.IP

NextIP returns IP incremented by 1

func NormalizeIP

func NormalizeIP(ip *net.IP)

NormalizeIP will transform the given ip to the 4 byte len ipv4 if possible

func PrevIP

func PrevIP(ip net.IP) net.IP

PrevIP returns IP decremented by 1
