Types

type Address 

type Address interface {
	IP() net.IP     // IP of this Address
	Domain() string // Domain of this Address
	Family() AddressFamily

	String() string // String representation of this Address
}

Address represents a network address to be communicated with. It may be an IP address or domain address, not both. This interface doesn't resolve IP address for a given domain.

func DomainAddress
