which ip address is not a network address course hero

What is the host address of an IP address?

It defines the first 64 bits as the network address and the last 64 bits as the host address. The following image shows how IPv6 separates the network address and host address in an IP address. How do host addresses work?

What are the components of an IP address?

An IP address consists of two components: the network address and the host address. The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet. If a large computer network is divided into smaller groups, each group is known as a subnet.

What is the difference between host address and subnet address?

The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet. If a large computer network is divided into smaller groups, each group is known as a subnet.

What is the host address of PC1 PC2 PC3 PC4 PC5 and PC6?

Host addresses of PC1, PC2, PC3, PC4, PC5, and PC6 are .1, .2, .3, .4, .5, and .6, respectively. In IP addresses, network addresses are always written before host addresses. If we write the network address before the host address of a PC, we will get the IP address of that PC.

What is the IP address of a computer?

Addresses in computer networks are known as IP addresses. An IP address consists of two components: the network address and the host address. The network address is used to find the subnet in which the computer or the device is located and the host address is used to find the computer or the device in the subnet.

Why do computers use IP addresses?

In a busy network where interfaces process millions of packets per second, an overlap of IP addresses can bring the entire network down. To avoid such a situation , computer networks use a unique IP address on each interface.

What is the purpose of a gateway router?

A gateway router is the router that connects the subnet to other subnets of the network. The gateway router forwards the data packet to the router that is connected to the destination subnet or know how to reach the destination subnet. To forward data packets, routers use only network addresses.

What is IPv4 subnet mask?

Subnet Mask. To separate network addresses from host addresses, IPv4 uses an additional component with IP addresses. This component is known as a subnet mask. In other words, in an IP address, how many bits are used in the network address and how many bits are left for the host address is determined by the subnet mask.

How many bits does a subnet mask have?

The subnet mask is also 32 bits in length and uses the same notation that is used by the IP address. The subnet mask assigns an individual bit for each bit of the IP address. If an IP bit belongs to the network portion, the subnet mask will turn on the assigned bit.

How many bits are in IPv4?

IPv4 addresses are 32 bits in length. These bits are divided into four equal sections. Sections are separated by periods and written in a sequence. In measurement, 8 bits are equal to one byte or an octet. In simple words, an IP address consists of four bytes or octets separated by periods.

How many versions of IP addresses are there?

There are two versions of IP addresses: IPv4 and IPv6. The length of IP addresses is different in both versions. Both versions also use different formats to differentiate between network addresses and host addresses. Let's understand IP addresses in both versions.

Why is IP address important?

This means that IP addresses are more hierarchical and easier to store data about than physical addresses are.

How many bits are in an IP address?

IP addresses are a 32 bit long numbers made up of four octets, and each octet is normally described in decimal numbers. 8 bits of data or a single octet can represent all decimal numbers from 0 to 255. For example, 12.30.56.78 is a valid IP address, but 123.456.789.100 would not be because it has numbers larger than could be represented by 8 bits. This format is known as dotted decimal notation. Will deep dive into how some of this works in an upcoming lesson about subnetting. The important thing to know for now is that IP addresses are distributed in large sections to various organizations and companies instead of being determined by hardware vendors. This means that IP addresses are more hierarchical and easier to store data about than physical addresses are. Think of IBM, which owns every single IP that has the number 9 as the first octet. At a very high level, this means that if an Internet router needs to figure out where to send a data packet intended for the IP address 9.0.0.1, that router only has to know to get it to one of IBMs routers. That router can handle the rest of the delivery process from there. It's important to call out that IP addresses belong to the networks, not the devices attached to those networks. So your laptop will always have the same MAC address no matter where you use it, but it will have a different IP address assigned to it at an Internet cafe than it would when you're at home. The LAN at the Internet cafe, or the LAN at your house would each be individually responsible for handing out an IP address to your laptop if you power it on there. On a day-to-day basis, getting an IP address is usually a pretty invisible process. You'll learn more about some of the technologies that play in a later lesson. For now, remember that on many modern networks you can connect a new device and an IP address will be assigned to it automatically through a technology known as dynamic host configuration protocol. An IP address assigned this way is known as a dynamic IP address. The opposite of this is known as a static IP address, which must be configured on a node manually. In most cases static IP addresses are reserved for servers and network devices, while dynamic IP addresses are reserved for clients. But there are certainly situations where this might not be true.

What does 9.0.0.1 mean?

At a very high level, this means that if an Internet router needs to figure out where to send a data packet intended for the IP address 9.0.0.1, that router only has to know to get it to one of IBMs routers. That router can handle the rest of the delivery process from there.

What is the difference between static and dynamic IP addresses?

In most cases static IP addresses are reserved for servers and network devices, while dynamic IP addresses are reserved for clients. But there are certainly situations where this might not be true.

Does my laptop have the same MAC address?

It's important to call out that IP addresses belong to the networks, not the devices attached to those networks. So your laptop will always have the same MAC address no matter where you use it, but it will have a different IP address assigned to it at an Internet cafe than it would when you're at home.
