IPv4 Addressing For IP version 4, each TCP/IP host is identified by a logical IP address. The IP address is a Network layer address and has no dependence on the Data-Link layer address (such as a MAC address of a network adapter). A unique IP address is required for each host and ...

Table 1 Feature Information for Auto-IP Feature Name Releases Feature Information Auto-IP The auto-IP feature addresses the problem of manually reconfiguring nodes during insertion, deletion, and movement of nodes within an auto-IP ring. The auto-IP feature automatically provides IP a...
That means global addressing.Address SpaceIPv4 has a certain address space. An address space is the total number of addresses used by the protocol. If a protocol uses N bits to define an address, the address space is 2NIPv4 uses 32-bit address format, which means that the address space ...
The following example shows the more common representation of classless IPv4 addressing:複製 172.16.16.1/20 The /20 represents how many leftmost subnet bits are set to 1 in the mask. This notation style is called CIDR. This subnet mask in binary notation would look like this:...
IPv4 Addressing This section covers some of the basic concepts of IPv4 addressing, such as how the Internet's address architecture uses the binary and dotted-decimal versions of IPv4 addressing. This section also reviews the structure of IPv4 addresses, such as the various classes of IPv4 addresse...
