Next, consider the potential value of the first (leftmost) bit place. Is 128 less than 209 Because it is, you should write a 1 beneath the 128 on your scratch paper and then write a 128 off to the side to keep tally of the running subtotal.

Move to the next potential value. Is 128+64 less than 209 The sum of these values is only 192, so again, you should write a 1 beneath the 64 and then a 64 to your running subtotal.

The next potential value is 32, but if you were to add a 1 here, you would achieve a subtotal of 224. This exceeds the target total of 209, so you must place a zero in the third bit place of the octet and not add anything to your running subtotal.

Next, the fourth bit potential value is 16; adding this value to 192 results in a subtotal of 208. Is 208 less than 209 Because it is, you should add a 1 beneath the 16 and a 16 to your running subtotal.

Lesson 2: Understanding IP Version 4 (IPv4) Addressing
Because you only need to add a value of 1 to achieve the target value of 209, placing a 1 in the eighth bit place will complete the translation of the octet.
128 1 64 1 32 0 16 1 8 0 4 0 2 0 1 1 Subtotal 128 64 16 +1 =209
The first octet is therefore written as follows in binary notation: 11010001
Understanding Routing and Default Gateways
The calculation of the network ID by using the subnet mask is a vital step in IPv4 communication because the network ID essentially tells a computer how to send an IPv4 packet toward a destination. When a computer on a network needs to send a packet to a remote address, the computer compares its own network ID to that of the destination network ID specified in the IPv4 packet. (To determine these network IDs, the computer always uses its locally configured subnet mask.) If the two network IDs match, the message is determined to be local and is broadcast to the local subnet. If the two network IDs do not match, the computer sends the packet to an address known as the default gateway. The router found at this default gateway address then forwards the IPv4 datagram in a manner determined by its routing tables. Figure 1-32 illustrates this process of IP routing. In the figure, a computer whose address is 192.168.100.5/24 needs to send an IP packet destined for the address 192.168.1.10. Because the network IDs of the two addresses do not match, the computer sends the packet to the router specified by the default gateway address. This router consults its routing tables and sends the packet to the router connected to the 192.168.1.0 network. When the router connected to this network receives the packet, the router broadcasts the packet over the local subnet. The destination computer at the address 192.168.1.10 responds to the broadcast and receives the packet for internal processing.

Remember also these essential points about routing and default gateways:
A default gateway must share the same network ID and be located within the same broadcast domain as the hosts it is serving. If a host has no default gateway setting configured, that host will be unable to connect to the Internet or to any computers beyond broadcast range. For example, a private internal server that occasionally needs to download content from the Internet needs to have a default gateway configured. Leaving the default gateway setting unconfigured on a host prevents access to that host from all points beyond the local subnet. In certain situations, therefore, you might in fact want to leave the default gateway setting unconfigured for security reasons.
