https://github.com/golang/go/blob/master/src/net/ipsock.go#L204

type addrList []Addr
func internetAddrList(net, addr string, deadline time.Time) (addrList, error)

However the internetAddrList only return one valid address.
I proposal split addr string by "," and return REAL addrList.

See filterAddrList in ipsock.go. It certainly returns a list of addresses.

No, I mean in

net.Listen
    |->net.resolveAddrList
           |-> net.internetAddrList

and at https://github.com/golang/go/blob/master/src/net/ipsock.go#L244
if addr string is an valid IPv4/IPv6 it would nether return multi addresses nor call filterAddrList

Can you please elaborate your problem? I don't understand what's the problem.

For example, If I want to listen to both 127.0.0.1 and 10.0.0.1
net.Listen can't do it.

You didn't explain your problem. I'm still not sure what's your problem but looks like you want to have a single control knob that handles multiple address families, endpoints and subflows. So this is a duplicate of #9334.
