Table 1-1 IP address classes and ranges Class Range Description A 0.0.0.0 to 127.255.255.255 IP addresses with all-0 host IDs are network addresses and are used for network routing. IP addresses with all-1 host IDs are broadcast addresses and are used for broadcasting packets to all...
Table 8-54 IP address classes and ranges Class Range Description A 0.0.0.0 to 127.255.255.255 IP addresses with all-0 host IDs are network addresses and are used for network routing. IP addresses with all-1 host IDs are broadcast addresses and are used for broadcasting packets to all...
Figure 1. Classes of IP Addresses The class of address of the IPv4 network is determined from the first 4 bits in the first octet of the IP address.Figure 2shows how the class of address is determined. Figure 2. Determining the Class of an IP Address 32-bit address xxxxxxxx xxxxxxxx xxx...
IPv4 Address ClassesThe IPv4 address space can be subdivided into 5classes-Class A, B, C, Dand E. Each class consists of a contiguous subset of the overall IPv4address range.With a few special exceptions explained further below, the values of theleftmost four bits of an IPv4 address determi...

Internet Address Classes The Internet community originally defined address classes to accommodate different types of addresses and networks of varying sizes. The class of address defined which bits were used for the network ID and which bits were used for the host ID. It also defined the possible...
IPv4 multicast addresses are defined by the class D Internet address class: 224.0.0.0/4. IPv4 multicast addresses range from 224.0.0.0 through 239.255.255.255. IPv4 multicast addresses for the 224.0.0.0/24 address prefix (224.0.0.0 through 224.0.0.255) are reserved for local subnet multicast traff...
and the need for internet access and the APIPA address range a location without DHCP but the need to communicate between computers (such as a workgroup), without reconfiguring IP settings. Additionally, this is useful for troubleshooting DHCP. If the computer has an address from th...
IP Address Classes In order to provide some structure to the way IP addresses are assigned, IP addresses are grouped into classes. Each class has a range of IP addresses. The range of IP addresses in each class is determined by the number of bits allocated to the net...
A subnet is a network segment. Single or multiple routers separate the subnet from the rest of the network. When your Internet service provider (ISP) assigns a network to a Class A, B, or C address range, you often must subdivide the range to match the network’s physical lay...
