# IP restriction

IP restriction adds an extra layer of security to your knowledge base by allowing or restricting access based on user-specified IP addresses.

> [!NOTE]
> ** NOTE
> 
> - This is a **project-level** setting. Once enabled, it applies across all workspaces and languages within that project.
> - Document360 supports both **IPv4** and **IPv6 (Unicast)** addresses.

## Accessing the IP restriction page

To access the IP restriction page:

1. Navigate to **Settings** (**) > **Knowledge base site** in the left navigation bar****in the Knowledge base portal.
2. In the left navigation pane, navigate to **IP restriction.**

The IP restriction page displays the following fields:

![](https://cdn.document360.io/860f9f88-412e-4570-8222-d5bf2f4b7dd1/Images/Documentation/IP%20restriction(1).png)
  - **Add my current IP address**: Click to automatically detect and add your current IP address.
  - **Friendly name**: Enter a name to identify the IP restriction. (No character limit)
  - **IP address**: Add a specific IP or a range (supports IPv4 and IPv6).
  - **Allow/Block**: Choose whether to allow or block the entered IP address/range.
  - **Remove**(**): Delete the restriction using the **Remove** (**) icon.
  - **Save**(**): Save your IP restriction changes using the **Save** (**) icon.

### Adding IP restriction

To add an IP restriction:

1. Click **Add IP address**.
2. Enter a name in the **Friendly name** field (mandatory).
3. Enter a valid **IP address** or a range.

Example of range: `79.15.135.189 - 79.15.135.229`
4. Click the **Save** (**) icon.
5. To clear entered details, click the **Reset** (**) icon.

Click **Add my current IP address**to add your currently used IP.

**Supported IPv6 formats:**

Here are some examples of valid and invalid IPv6 formats:

| Format | Status |
| --- | --- |
| `2001:0db8:85a3:0000:0000:8a2e:0370:7334` | ✅ Valid |
| `2001:0db8:85a3::8a2e:0370:7334` | ❌ Invalid |
| `2001:db8:85a3:0:0:8a2e:370:7334` | ✅ Valid |

### Allow/Block an IP address

You can find two options for each IP:

- **Allow**: Grants access to the Knowledge base site.
- **Block**: Restricts access from the specified IP.

> [!NOTE]
> ** NOTE
> 
> If the same IP is entered for both Allow and Block, or added more than once, a warning will appear: “**A restriction with this IP address already exists.**”

### Deleting an IP restriction

To delete an IP restriction, click the **Delete** (**) icon next to the IP address.

A confirmation message will appear as **IP restriction deleted.**

> [!NOTE]
> ** NOTE
> 
> Deleting an IP restriction is permanent and cannot be undone.

## Troubleshooting

### **Preventing DDoS attacks when IP restriction is enabled**

Enabling IP restriction provides a layer of access control, but it may not be enough to prevent Distributed Denial of Service (DDoS) attacks. These attacks flood your system with fake traffic, potentially slowing down or blocking access for legitimate users.

To enhance your protection, combine IP restrictions with additional security measures like IP whitelisting, blacklisting, and DDoS protection tools.

**Steps to resolve:**

1. [**Enable IP whitelisting**](/help/docs/csp-guidelines-for-document360-widget) Allow access only from trusted and known IP addresses. This helps limit exposure and prevents unauthorized access.
2. **Use IP blacklisting** Block IP addresses that display suspicious or malicious behavior, such as repeated failed login attempts.
3. **Review and update regularly** Periodically review and update your whitelist and blacklist to stay ahead of evolving threats and usage changes.
4. **Leverage a DDoS protection service** Use services like **Cloudflare**, **AWS shield**, or **Azure DDoS protection**. These tools detect and block high-volume attack traffic before it reaches your infrastructure.

### FAQ

#### What is an IP address?

An IP address (Internet Protocol address) is a unique number that identifies a device on a network and allows it to send or receive data over the internet.

#### What is an IPv4 format?

An IPv4 address has four groups of numbers (0–255) separated by dots.

Example: `49.206.113.170`

#### What is an IPv6 format?

An IPv6 address uses 128-bit formatting and includes hexadecimal values separated by colons.

- Example: `FE38:DCE3:124C:C1A2:BA03:6745:EF1C:683D`
- **Start of range**: `0000:0000:0000:0000:0000:0000:0000:0000`
- **End of range**: `ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff`

#### What is an IPv6 unicast address?

An IPv6 unicast address identifies a single, specific device on a network. When data is sent to this address, it goes directly to that one device—ensuring point-to-point communication. This is different from multicast (one-to-many) or anycast (one-to-nearest) addresses, which are used for broader or optimized delivery.
