Functions

func IPv6Available

func IPv6Available(ctx context.Context) bool

IPv6Available is like SupportsIPv6, but always do the check without caching.

func IsIPv6

func IsIPv6(ip string) bool

IsIPv6 checks if the provided IP is v6.

func IsLinkLocalUnicastIPv6

func IsLinkLocalUnicastIPv6(ip string) bool

IsLinkLocalUnicastIPv6 checks if the provided IP is a link local unicast v6 address.

func SupportsIPv6ListenLocal

func SupportsIPv6ListenLocal() bool

func Up

func Up() bool

Types

type ParallelDialer

	net.Dialer
}

func (*ParallelDialer) DialContext
