The simple answer is: the IP address(es) shown by 'ifconfig' will be the ones actually bound to that interface on that machine. Without knowing *how* you're binding those addresses, we can't tell you which of your 25 "static" addresses are bound on any particular machine. In most cases, I expect static addresses to be directly configured on the specific machine in question. Since you control that machine, and don't know what address(es) are configured, that probably isn't the case. As a second possibility, the addresses are allocated statically, but the host is configured via DHCP, from a server that knows those addresses are statically assigned to that host by hardware address or some other DHCP option. In this case, there will almost certainly be exactly one of your 25 static IP addresses bound to this specific host's network interface. But, again, the key piece of information is how the addresses are getting bound.
