2. IP Address: An IP address is an adress used in order to uniquely identify a device on an IP network. It is made up of 32 binary bits which can be divisible into a network portion and host portion with the help of a subnet mask. 32-bits are brokern into 4 octets(8 bits = 1...
For this process to work, an IP address has two parts. The first part of an IP address is used as a network address, the last part as a host address. If you take the example 192.168.123.132 and divide it into these two parts, you get 192.168.123. Network .132 Host or 192.168...
IPv4 allows for a variation of the network and host segments of an IP address, known assubnetting, can be used to physically and logically design a network. For example, an organization can have a single internet network address (NETID) that is known to users outside the organization, yet ...
Broadcast address: This is always the last address of the subnet. A packet forwarded to the broadcast address is broadcasted to all the addresses in a subnet. Subnet mask (or) netmask: This is the bitmask used to identify the subnet of an IP address by applying bitwise AND operation with...
IP interfaces have IP addresses Each IP interface must have its own unique IP address Internally, this is represented as a 32-bit number of 0’s and 1’s IP addresses consist of two partsnetwork identification host identificationSlide 4Breaking it up into network number and host is keyNetwork...
What is an IP address? In order to understand subnets, we must quickly define IP addresses. Every device that connects to the Internet is assigned a unique IP (Internet Protocol) address, enabling data sent over the Internet to reach the right device out of the billions of devices connected...
The slash notation (/) means how many bits are turned on (1’s). Obviously, the maximum could only be /32 because a byte is 8 bits and there are four bytes in an IP address: (4×8=32). In the example, 192.168.10.32/28 means the address range provided including subnet...
Subnettingis a method for maximizing the limited 32-bit IPv4 addressing space and reducing the size of the routing tables in a large internetwork. With any address class, subnetting provides a means of allocating a part of the host address space to network addresses, which lets you have more ...
Figure 1-4 Subnetting of IP addresses The Class B IP address shown in Figure 1-4 is used as an example. Assume that the network address is 172.16.0.0 and the mask is 255.255.0.0. The two left-most bits of the host ID are used as the subnet ID. The subnet ID ranges from 00 to ...
IP address allocation within an organization requires a lot of long-term planning. This timely publication addresses the administrator and engineer's need to know how IP 6 impacts their enterprise networks * Ideal for companies planning a phased migration from IP 4 to IP 6 * Timely publication:...
