What is the equivalent of listening on a port on IPv4?
I believe that listening on a port on 0.0.0.0 is equivalent to listening on a port on any network adapter, at least my memory of the Windows socket API says that this is so. That is correct. 0.0.0.0 is defined as INADDR_ANY and can be used to listen on all local IPv4 adapters.
Can an IPv6-only listener listen on an IPv4 adapter?
An IPv6-only listener cannot listen on an IPv4 adapter and cannot accept IPv4 clients. However, a dual-stack listener bound to INADDR6_ANY can bind to IPv4 and IPv6 adapters and accept both IPv4 and IPv6 clients, where IPv4 addresses are reported by accept (), WSAAccept (), and getpeername () as IPv4-mapped IPv6 addresses.
