# Register an Alias (DIONS)

After downloading and installing your wallet and setting up a password you can register an alias, also known as a DION. Before we explain how to register a DION we’ll explain what it is and what you can do with it. _Alias_ and _DION_ can be used interchangeably.

## **What is DIONS?** <a href="#what-is-dions" id="what-is-dions"></a>

DIONS stands for Decentralized Input Output Names Server and it is a feature that does something similar to what DNS (Domain Name System) does. Like a website address (e.g. [https://www.iocoin.io](https://www.iocoin.io/)) is another name (an alias) for an IP address where the website is hosted, a DION is another name for an I/O Coin address. This is very handy in situations where you want to send IOC to a friend for example because you don’t have to remember their whole 34-digit public address, only their DION.

## **What else can you do with DIONS?** <a href="#what-else-can-you-do-with-dions" id="what-else-can-you-do-with-dions"></a>

Besides the above-mentioned example you can also use your alias to store any document up to 1MB on the blockchain and if you wish you can also transfer the ownership of this alias to someone else and therefore transfer the document to this person. All of this is secured with an AES256 encryption. You can read more about storing and transferring documents [here](store-and-transfer-documents). A third use for aliases is that you can use them to chat with a friend via an AES256 encrypted tunnel so noone can spy on your private conversations. How do I chat with a friend you may ask? Read all about it [here](send-encrypted-messages).

## **So how do you create a DION?** <a href="#so-how-do-you-create-a-dion" id="so-how-do-you-create-a-dion"></a>

Open your wallet, unlock it and do either one of the following: - Go to the **DIONS** tab, then choose **Create DION** at the top-right corner, or; - Go click **Create DION** in your wallet overview. Now you are on the Create DION page, click the **Choose an alias** button, choose an alias you like and hit **Enter**. If your preferred DION is still available you will get an overview like shown below, if your chosen DION is already in use you will be informed of that.

Note: DIONS only accepts alphanumerical characters (a-z, 0-9).

Now, check the **Everything looks good** box and then click **Create**. Done! You have registered your own DION!

A newly created DION is encrypted by default but you can choose to decrypt it by clicking the **Decrypt** button in your DIONS overview. Encrypted DIONS can be used for file storage and transfer whereas decrypted aliases (also known as public aliases) can be used for receiving payments and chatting.
