What is IPv6 -- Internet Protocol Version 6?

IPv6 (Internet Protocol Version 6) is also called IPng (Internet Protocol next generation) and it is the newest version of the Internet Protocol (IP) reviewed in the IETF standards committees to replace the current version of IPv4 (Internet Protocol Version 4).

IPv6 is the successor to Internet Protocol Version 4 (IPv4). It was designed as an evolutionary upgrade to the Internet Protocol and will, in fact, coexist with the older IPv4 for some time. IPv6 is designed to allow the Internet to grow steadily, both in terms of the number of hosts connected and the total amount of data traffic transmitted.

IPv6 is often referred to as the "next generation" Internet standard and has been under development now since the mid-1990s. IPv6 was born out of concern that the demand for IP addresses would exceed the available supply.
While increasing the pool of addresses is one of the most often-talked about benefit of IPv6, there are other important technological changes in IPv6 that will improve the IP protocol:
No more NAT (Network Address Translation)
Auto-configuration
No more private address collisions
Better multicast routing
Simpler header format
Simplified, more efficient routing
True quality of service (QoS), also called "flow labeling"
Built-in authentication and privacy support
Flexible options and extensions
Easier administration (say good-bye to DHCP)

What is IPv4 -- Internet Protocol Version 4?

IPv4
IPv4
IPv4 (Internet Protocol Version 4) is the fourth revision of the Internet Protocol (IP) used to to identify devices on a network through an addressing system. The Internet Protocol is designed for use in interconnected systems of packet-switched computer communication networks (see RFC:791). 
INTERNET PROTOCOL VERSION 4 (IPv-4)

IPv4 is the most widely deployed Internet protocol used to connect devices to the Internet. IPv4 uses a 32-bit address scheme allowing for a total of 2^32 addresses (just over 4 billion addresses).  With the growth of the Internet it is expected that the number of unused IPv4 addresses will eventually run out because every device -- including computers, smartphones and game consoles -- that connects to the Internet requires an address.
A new Internet addressing system Internet Protocol version 6 (IPv6) is being deployed to fulfill the need for more Internet addresses.

What is Cloud Storage

Cloud storage means "the storage of data online in the cloud," wherein a company's data is stored in and accessible from multiple distributed and connected resources that comprise a cloud.
Cloud storage can provide the benefits of greater accessibility and reliability; rapid deployment; strong protection for data backup, archival and disaster recovery purposes; and lower overall storage costs as a result of not having to purchase, manage and maintain expensive hardware. However, cloud storage does have the potential for security and compliance concerns.

There are four main types of cloud storage:

What is The Difference Between IPv6 and IPv4?

Confused by phrases like Internet Protocol (IP), IPv6, IPv4 and IPng? Webopedia explains the difference between IPv4 and IPv6, and looks at the topic of migrating to a 128-bit address space.

What is Internet Protocol -- IP?

IP (short for Internet Protocol) specifies the technical format of packets and the addressing scheme for computers to communicate over a network. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source.

IP by itself can be compared to something like the postal system. It allows you to address a package and drop it in the system, but there's no direct link between you and the recipient. TCP/IP, on the other hand, establishes a connection between two hosts so that they can send messages back and forth for a period of time.


There are currently two version of Internet Protocol (IP): IPv4 and a new version called IPv6. IPv6 is an evolutionary upgrade to the Internet Protocol. IPv6 will coexist with the older IPv4 for some time.

The Difference Between IPv6 and IPv4 IP Addresses

An IP address is binary numbers but can be stored as text for human readers.  For example, a 32-bit numeric address (IPv4) is written in decimal as four numbers separated by periods. Each number can be zero to 255. For example, 1.160.10.240 could be an IP address.
IPv6 addresses are 128-bit IP address written in hexadecimal and separated by colons. An example IPv6 address could be written like this: 3ffe:1900:4545:3:200:f8ff:fe21:67cf (see "What does an IPv6 address look like?")


Understanding IP Addressing


Every computer that communicates over the Internet is assigned an IP address that uniquely identifies the device and distinguishes it from other computers on the Internet.
(IP Address)

What is an IP Address?


An IP address is an identifier for a computer or device on a TCP/IP network. Networks using the TCP/IP protocol route messages based on the IP address of the destination.
Recommended Reading: Learn more about the TCP/IP protocol.
An IP address consists of 32 bits, often shown as 4 octets of numbers from 0-255 represented in decimal form instead of binary form. For example, the IP address: 168.212.226.204 in binary form is 10101000.11010100.11100010.11001100.

But it is easier for us to remember decimals than it is to remember binary numbers, so we use decimals to represent the IP addresses when describing them. However, the binary number is important because
that will determine which class of network the IP address belongs to.

What is an IP address?

Every device connected to the public Internet is assigned a unique number known as an Internet Protocol (IP) address. IP addresses consist of four numbers separated by periods (also called a 'dotted-quad') and look something like 127.0.0.1.

Since these numbers are usually assigned to internet service providers within region-based blocks, an IP address can often be used to identify the region or country from which a computer is connecting to the Internet. An IP address can sometimes be used to show the user's general location.

Because the numbers may be tedious to deal with, an IP address may also be assigned to a Host name, which is sometimes easier to remember. Hostnames may be looked up to find IP addresses, and vice-versa. At one time ISPs issued one IP address to each user. These are called static IP addresses. Because there is a limited number of IP addresses and with increased usage of the internet ISPs now issue IP addresses in a dynamic fashion out of a pool of IP addresses (Using DHCP). These are referred to as dynamic IP addresses. This also limits the ability of the user to host websites, mail servers, ftp servers, etc. In addition to users connecting to the internet, with virtual hosting, a single machine can act like multiple machines (with multiple domain names and IP addresses).

Was ist eine IP-Adresse?

Jedes Gerät, dass zum Internet verbunden ist, hat eine eindeutige Nummer zugewiesen, bekannt als Internet Protocol Adress (IP). IP Adressen bestehen aus vier Nummern, die durch Punkte (auch genannt "Dotted-Quad") getrennt werden. Eine Adresse kann so aussehen: 127.0.0.1.

Seitdem diese Nummern normalerweise einem Provider zugeordnet werden, der diesen Regionen zuteilt, kann eine IP Adresse dazu benutzt werden, die Region oder das Land herauszufinden, von dem ein Computer sich zum Internet verbindet. Manchmal kann eine IP Adresse sogar benutzt werden, um die exakte des Computers zu zeigen.

Weil es schwer ist, sich an solche Nummern zu erinnern, können IP Adressen einem Host Namen zugeordnet werden, an den man sich leichter erinnert. Host Namen können dazu verwendet werden IP Adressen zu finden und umgekehrt. Einst vergaben Provider IP Adressen an jeden Benutzer. Diese nennt man statische IP Adressen. Weil es nur eine begrenzte Anzahl an an IP Adressen gibt und da die Vergabe von IP Adressen stetig ansteigt, vergeben die Provider jetzt in einer dynamischen Art Adressen aus einer Gruppe von IP Adressen heraus (mittels DHCP). Diese bezeichnet man als dynamische IP Adressen. Das begrenzt allerdings auch die Fähigkeiten eines Nutzers Webseiten, Mail Server, FTP Server und andere zu hosten. Zusätzlich zu Nutzern die sich zum Internet verbinden, kann mit virtuellem Hosting eine einziger Rechner wie mehrere Rechner zusammen auftreten (Mit verschiedenen Domains, Namen und IP Adressen).

How do I change my IP address?

"How do I change my IP address?" and "Can I change my IP address?" are probably the most commonly asked questions. Please attempt the following then, if that does not work, visit the Change IP Address forum.

Before trying any other methods to change your IP address, try turning off (or unplugging the power of) your Cable/DSL modem for five minutes. In many cases this will change your IP address. However, if that does not change your IP address, repeat the process for 8 hours (overnight works well) instead of 5 minutes. Hopefully this will result in an IP change.

If the above does not result in your IP address changing, please look through the below for the situation that best matches yours and attempt to change your IP address that way. Unfortunately you are not able to get your IP address to change in all cases, as it is ultimately determined by your ISP's DHCP configuration (when you've got a dynamically assigned IP address, that is.)
