Is there a widely used way to write "any IP address" as a string?

Question

I've seen APIs that use "*" and "::" (for IPv6) to mean "any address" (i.e. INADDR_ANY) when binding a socket. I've also seen APIs that use "" or "0.0.0.0" to mean the same. Is there a widely use standard for writing "any address" as a string?

An IPv6 socket can connect to IPv4 via address mapping, thus in6addr_any and ::0 would be preferred. — Steve-o

Those are the two ways. Sadly there isn't one that works for both IPv4 and IPv6. When binding a socket you should certainly use INADDR_ANY.

It's such a good idea, that there's more than one widely used way to write that. Isn't programming fun?
