# Provision Public IPs in DynamicLink

Public IP addresses enable internet connectivity for your DynamicLink services. Request IPv4 or IPv6 blocks to use with Dedicated Internet Access (DIA) connections and other network services.

<Tip> You can request IPs in advance for network planning—you don't need an active port to request IP blocks. </Tip>

<Note>
  You will need a public IP block when provisioning a Dedicated Internet Access (DIA) connection.

  You can request your public IP addresses before provisioning your connection or as part of the [DIA provisioning process](dia-create).
</Note>

## Request a Public IP block

Go to **Build Your Network > Public IPs**. Click **Request IP** and complete the following fields:

| Field         | Description                                                                                                                                                                                                                                                                                  |
| ------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Name**      | Descriptive identifier (e.g., `production-dia-ips-chicago`).                                                                                                                                                                                                                                 |
| **Location**  | Metro location where IPs will be used.                                                                                                                                                                                                                                                       |
| **IPv4 Size** | You can select from the following: <br />`/29` = 8 usable IPs, <br />`/30` = 4 usable IPs<br />`/31` = 2 usable IPs                                                                                                                                                                          |
| **IPv6 Size** | This is preselected at `/64` and cannot be changed. <br /><br /> A `/64` block is the standard size for most IPv6 subnets because Stateless Address Autoconfiguration (SLAAC) requires a `/64`, and it gives each interface a 64-bit host identifier (often derived from MAC or randomized). |

Click **Request**.

## Use your IP blocks

View all assigned IP blocks in the **Public IPs** tab. When creating a DIA connection:

* Select an existing IP block from your pool, or
* Click **Request New** during connection setup to provision a block on the fly
