type UpnpAddressResolver

type UpnpAddressResolver struct {
	// contains filtered or unexported fields
}

func (*UpnpAddressResolver) Resolve

func (r *UpnpAddressResolver) Resolve(observedAddress ma.Multiaddr) (ma.Multiaddr, error)

Resolve checks if there is a possible better advertisable underlay then the provided observed address. In some NAT situations, for example in the case when nodes are behind upnp, observer might send the observed address with a wrong port. In this case, observed address is compared to addresses provided by host, and if there is a same address but with different port, that one is used as advertisable address instead of provided observed one. TODO: this is a quickfix and it will be improved in the future
