Which part of an IP address identifies the host?
The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. An example of a Class A IP address is 102.168. 212.226, where “102” identifies the network and “168.212. 226” identifies the host on that network.
How are hosts identified from networks using IP addresses?
An IP address is a 32-bit number. It uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network. IP addresses are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168. 123.132.
What protocol must be used to determine the IP address?
The protocol used by the router to assign IP addresses is called Dynamic Host Control Protocol (DHCP).
What is used to identify each part of an IP address?
For this purpose, an IP address is logically recognized as consisting of two parts: the network prefix and the host identifier, or interface identifier (IPv6). The subnet mask or the CIDR prefix determines how the IP address is divided into network and host parts. The term subnet mask is only used within IPv4.
Which is a 32 B IP address?
For information on IPv6 addresses, see IPv6 Addressing. The IPv4 address is a 32-bit number that uniquely identifies a network interface on a machine. An IPv4 address is typically written in decimal digits, formatted as four 8-bit fields that are separated by periods.
Which class of an IP address has the largest number of hosts?
Class A Public & Private IP Address Range Class A addresses are for networks with large number of total hosts. Class A allows for 126 networks by using the first octet for the network ID.
What does 255 mean in a subnet mask?
Class C Subnet Mask Examples 255 are the numeric values of three sets of eight 1 bits. The 0 means eight 0 bits. There are “no” subnets, and up to 254 hosts can be addressed in this network (255 minus 1).
Why is IPv4 32 bit?
IPv4 chose 32 bit because it was the biggest register found in any common processors at the time. It was an arbitrary choice that seemed good enough at the time. When IPv4 was originally devised we all believed it was sufficiently large enough. Few, if any, envisioned what happened 20+ years later.
Which is the host ID portion of an IP address?
In network addressing, the host address, or the host ID portion of an IP address, is the portion of the address used to identify hosts (any device requiring a Network Interface Card, such as a PC or networked printer) on the network. 1. Class A: 1.0.0.0 – 127.255.255.255
What are the characteristics of an IP address?
An IP host address identifies a device to which IP packets can be sent. An IP network address identifies a specific network segment to which one or more hosts can be connected. The following are characteristics of IP addresses:
What is the IP address used for broadcasting?
Broadcasting is an addressing technique available in IPv4 to address data to all possible destinations on a network in one transmission operation as an all-hosts broadcast. All receivers capture the network packet. The address 255.255.255.255 is used for network broadcast.
How are IP addresses assigned in a network?
Dynamic IP addresses are assigned by network using Dynamic Host Configuration Protocol (DHCP). DHCP is the most frequently used technology for assigning addresses. It avoids the administrative burden of assigning specific static addresses to each device on a network.
