What are the 3 types of IPv6 addresses?

Answer 1

There are 5 defined Classes for IP Addresses:

Class A: 0.0.0.0 - 127.255.255.255

Class B: 128.0.0.0 - 191.255.255.255

Class C: 192.0.0.0 - 223.255.255.255

Class D: 224.0.0.0 - 239.255.255.255

Class E: 240.0.0.0 - 255.255.255.255

Answer 2

There are static and shared IP addresses used for access to websites but I am not sure that is what was meant by the person who posted the question. So, I will answer from another point of view.

For networks, there can be two types of IP addresses: public and private. The public IP address is what is used to communicate with the internet, such as 24.124.0.131 This is known as a routable address and anyone on the Internet can access it. However, not everything that is connected into a network needs to be seen on the Internet, so three private IP address ranges were set up for internal use and, by definition, are not routable. Those address ranges are:

10.0.0.0 through 10.255.255.255 (allowing 16,777,216 total addresses)

172.16.0.0 through 172.31.255.255 (allowing 1,048,576 total addresses)

192.168.0.0 through 192.168.255.255 (allowing 65,536 total addresses)

The most commonly known private address range is, of course, the last in the list since that is what is typically assigned to routers by the manufacturers. Using any of the above address ranges, one can configure a private network of any appropriate size for internal communication and when necessary, all devices can access the Internet through a router that performs a task called Network Address Translation (NAT). As far as any Internet resource knows, it is the router that is making the request since it is the public IP address assigned to that router by the Internet Service Provider (for example, the local cable company in the case of cable modem Internet access) that the specific website (or whatever else) sees. When the information is received, the router then sends that information to the actual machine that requested that information by using its private IP address.

To explain further, let's say that Mary wants to print to a network printer down the hall from her office. Since both her computer and the printer are in the office network, both have private IP addresses. For the sake of argument, let's say that the computer is at 192.168.1.117 and the printer is assigned 192.168.1.129. When the router sees the communication from Mary's computer, it knows that since the request is using a private IP address, it will not need to be sent over the Internet connection, so it instead forwards the request over to the printer at its appropriate IP address. However, let's say that Mary's computer realizes that it is time for a virus definition update and wants to get the updates from the Symantec update server, it sends a request to 198.63.231.41 to obtain said updates. The router sees this request and realizes that the computer needs something from outside, so it sends the request out to the appropriate Internet server and reverses the process when the updates start arriving for the computer.

The reason that private IP addresses are important and necessary is that without them, there could easily be IP address conflicts that would disallow access to certain resources. For example, if there were no private IP address ranges and this hypothetical company's IP address range fell into the 198.63.231.x address range, when Mary's computer tried to access the Symantec update server, the router would look at the request and route it internally to whatever was assigned that address on the local network rather than sending it out to Symantec server. Since presumably the internal address would not have a duplicate of the Symantec server, the update would not be available and appropriate communication for this request would be broken.

I hope this helps. If you have other questions or if you were trying to understand something else that neither Padmashreekv or I discussed, feel free to drop me a line and let me know. I'm glad to do what I can to make this clear for you.

IP addresses are basically of two types:

1) Static IP address

2) Shared IP address

An IP Address is a 32-bit number that identifies a computer on the Internet. Every web site on the internet is found not by its domain name but by its IP address.

When someone types the address: www.xyz.com it is translated into an IP address and then the computer is directed to that IP address which is the web site.

Now every single website has an IP address specifically allocated to it. If every site assigned a separate IP address then there could be a problem with running out of IP addresses so a lot of the sites on the server use a single IP address for multiple sites.

Thus, using more than one site on an IP address is called a Shared IP address. If a site has its own IP address, and shares with no one else, it is called a Static IP address.

You can always access a site which has a static IP address by using its IP address alone, but you can not access a site using a shared IP address by typing in the IP address alone because when you type in a shared IP address you arrive at the server but the server does not know which site you are looking for as you have not told it which domain name you want.

Requirement of static IP address:

1) The main reason to have a static IP address for your site is that, you can use SSL encryption on a static IP address only. In order to transmit sensitive data over the internet, it must be encrypted to prevent someone from intercepting the information.

2) In case if the site needed the anonymous ftp access(anyone can download files of the site), the site needs to have a static IP address.

Other than these two reasons there is no need for a site to have its own IP address.

Answer 4

There are 2 types of IP addresses static and dynamic IP

When a device is assigned a static IP address, the address does not change. Most devices use dynamic IP addresses, which are assigned by the network when they connect and change over time.
