What are the 5 IP address classes range?

What are the 3 private IP address ranges that are used?

All you need to know is that they are the public IP address ranges of the private IP addresses used for network traffic on each of your servers/PCs.

What do I care if my server "owns" a given private IP address? It doesn't own any private IP address. Does a specific subnet have its own reserved IPs or what?
And no, you will never be able to block a user by trying to redirect their IP. You must block the IP of the user's computer/server, because there can be so many users using that IP.

From an end point (or in my case, a corporate) perspective, they are the end points of a network. This is the only way you know what you can reach. With that understanding, it is quite easy to implement blocking from the end point's point of view. This makes sense when you have a large network with many users.

If we're at home and one of the computers connected to our home network gets hijacked, then a lot of IP packets start getting routed to a different domain. From my point of view, the machine that was hijacked suddenly becomes a threat to our network as it is receiving unwanted IP traffic.

Now, if I'm on a local network in which our home PC is connected to a router that shares the internet connection with several other users. It would not be very easy for me to simply block certain domains from a single point of view, assuming I'm sitting behind a router that allows incoming/outgoing connections from multiple networks.

What are the 4 types of IP addresses?

How long does it take before my subnet expires?

What are the four types of IP addresses? I'm a little bit confused about what all the different types of IP addresses actually are. I'm starting to understand that each IP address has to do with a different purpose. But, for example, I am still not sure what a Class A and Class B is used for in this context. Can someone shed some light on that please?

IP addresses are simply assigned to entities. The first digit denotes the network, the second denotes the number of interfaces. Example: IPv4: 10.0/8 RFC1918 Range: 1) 10.0 - 10.255
2) 172.16.0 - 172.31.255
RFC6598 Range: 1) 169.254.0 - 169.127.255
2) 192.168.0 - 192.255
As you can see, 10.0 (networks that have only one interface), 172.0 (Networks with only 16 interfaces) and 192.0 (only 7 interfaces, from 10.0) are addresses in RFC1918 while 169.255 are addresses in RFC6598.

Classes A, B, and C are ranges. Class Networks which never have to be routed. These networks are always directly connected to the origin router. Examples: 10.0/8, 172.0/12
Class B: Networks which require routing. These networks always use the routers. Examples: 172.0/12, 10.0/23, 192.0/16
Class C: Networks which might be routed. This type of network can be routed between hosts. Examples: 192.0/24, 172.

What are the 5 IP address classes range?

We'll answer this question step by step.

We start with a quick refresher: The IP address system is divided into three parts: The subnet (network) address range from address 0 to 127 - or the first 128 addresses. These are usually represented in dotted-quad notation as x. The class C network address range from 128 to 191 - or the next 64 addresses. These are represented in dotted-quad notation as x. The class B network address range from 192 to 223 - or the next 32 addresses.

In a nutshell, the IP address system has eight classes ranging from class A up to class G. You can find the full list of address ranges at the following link: The following figure represents the IP address classes ranges: For each class, we now have a detailed breakdown of the addresses. The class A. We'll begin with the class A network address range. The class A address range extends from 0 to 127. In this range, all the addresses are allocated to private networks.

IP addresses in this class are used for private network and can be called private addresses. These addresses are assigned to organizations and individuals for the use of their internal networks. In a nutshell, private addresses are used to connect computers inside a LAN. We'll now look at the class B network address range. The class B address range extends from 128 to 223. In this range, we find all the common addresses used for Internet connectivity.

These addresses are used to connect Internet traffic between network devices and hosts. Classes B and C are mostly used for private networks. However, it's important to note that there are different types of networks. You can use a class B address for example to connect two computers on a LAN in one subnet. Classes B and C are often used to connect hosts, for example. Class D. We'll now move on to class D addresses. The class D address range extends from 224 to 247.
