A network engineer is setting up a local network and needs to calculate IP addresses for connected devices. The IP address of the router in binary is 11000000.10101000.00000001.00000001 (192.168.1.1 in decimal), and she wants to assign the first device the next IP address. What would this next IP address be in binary?
