What this does it create a binding on the address 0.0.0.0 (and ipv6's equivilent, ::); it will accept connections on that port via any address that the system has, including the localhost address at 127.0.0.1, as well as any and all configured IP addresses.

The reason that this is configurable is if you are looking to have a different web site accepting connections on several different configured IP addresses on the same server. (however, this approach is not necessary for hosting multiple sites; utilizing host headers with 1 IP address and leaving the IP set to "All Unassigned" is generally preferable)
