Actually you can't get that just from the ip packet by itself, the ip packet just contains the source and destination ip . You can have an idea of the subnet but no the exact subnet the host belongs to. If you sniff arp request you may have a better idea the subnet used just keeping a record of the destination asked

The IP packet will not contain any subnet info.
