 | | Subnet mask 255.254.0.0 Decimal = 11111111 11111110 00000000 00000000 Binary. | | | The problem with this subnet is that the unicast address for the subnet is the same as the unicast address for the entire class A network. | | | Thus we have a subnet number of 10 and an extended network address of 12.10.0.0 (decimal) = 00001100 00001010 00000000 00000000 (binary) (Bitwise AND of 12.11.10.9 with 255.254.0.0). |

| | Cisco - Subnet Zero and the All-Ones Subnet |
| | Subnet zero is also known as the all-zeros subnet. | | | Also, when you write the binary equivalent of the subnet zero address, all the subnet bits (bits 17, 18, and 19 in this case) are zeros. | | | The use of the all-ones subnet was explicitly allowed and the use of subnet zero is explicitly allowed since Cisco IOS Software Release 12.0. |

| | Subnet masks also use 32-bit long IP addresses that always use all binary 1s in the network and subnetwork portions of the address and all binary 0s in the host portion of the address. | | | IP addresses ending in all binary 0s are reserved for the network. | | | When class "C" IP addresses are written in binary format, the first three bits will always be a 1, a 1, and a 0. |

| | IP Subnet Calculations |
| | Many subnets are physically isolated from the rest of the network by a device such as a router or a switch. | | | To do this we compare the binary representation of the pertinent octet of the subnet mask witht he binary representation of the corresponding octet in the IP address. | | | Now the third octet of all the addresses on this network are part of the network field instead of the host field. |

| | In a Class B address, the first two octets are the network portion, so the Class B example in Figure 1 has a major network address of 172.16. | | | In a Class A address, the first octet is the network portion, so the Class A example in Figure 1 has a major network address of 10. | | | Notice that each of the routers in Figure 2 is attached to four subnetworks, one subnetwork is common to both routers. |

| | The number of bits borrowed from the host field determines the number of subnets, and also the maximum number of nodes on each subnet. | | | For example in a Class A address we could borrow 5 bits from the host part, for a network address of 23.0.0.0, the subnet mask would be: | | | Thus, for example, a Class B address has 16 bits in the host field. |

| | Get a Clue: Calculating Subnet Masks |
| | Refer to our first address example of 63.26.15.5 with a subnet mask of 255.255.255.0 in binary. | | | In this example, it is only the last segment that changes from one host to another; this last segment is known as the host address; the first 3 segments, for this example, make up the network address. | | | Fromt he same logic we know about all the bits for the entwork masks because of the same reason, the network address matches up with all the 1s in the subnet mask. |

| | Subnetting can help overcome distance limitations of physical networks by dividing up a physical network into individually addressed networks so they can be connected logically with routers. | | | These 32-bit IP addresses are almost always written as four dot-separated decimal numbers, one for each byte of the address. | | | Using the maximum number of hosts on one Ethernet segment is generally not good practice because it could create performance problems due to network congestion. |

| | IP address: Information From Answers.com |
| | An IP address (Internet Protocol address) is a unique number, a kind of telephone number, used by machines (usually computers) to refer to each other when sending information through the Internet. | | | Although the next version of the IP protocol offers a virtually unlimited number of unique addresses (see IPv6), the traditional IP address (IPv4) uses a 32-bit number that defines both the network and the host computer. | | | The network class determines how many of the 32 bits are used for the network address, leaving the remaining bits for use as the host number (note the numbers of networks and hosts in the table below). |
