IP visibility

import { Render, Details } from "~/components";

DEX's IP visibility gives administrators insight into three different IP types per device:

1. Device: The private IP address of an end-user device.
2. ISP: The public IP that the ISP assigns when it routes the end-user device's traffic.
3. Gateway: The router's private IP (the router the end device is connected to.)

:::note

The ISP IP is only visible to users with the Zero Trust PII role.

DEX's IP visibility supports both IPv6 and IPv4 addresses.

IP information helps IT administrators troubleshoot network issues and identify device locations. Common uses include:

• Identifying which access point or network segment a user is connected to
• Verifying that network access control (NAC) policies are applied correctly
• Diagnosing firewall restrictions on specific VLANs (virtual local area networks)
• Troubleshooting Layer 2 (data link layer) and DHCP (Dynamic Host Configuration Protocol) issues
• Indirectly determining user identity and device location

View a device's IP information

To view IP information for a user device:

1. In Cloudflare One, go to Team & Resources > Devices > Your devices.
2. Select a device, then select View details.
3. Go to IP details.
4. Review the IP details for your selected device's most recent session.

View a device's IP history

DEX's IP visibility allows you to review an event log of a device's IP history for the last seven days. To view a device's IP history:

1. In Cloudflare One, go to Team & Resources > Devices > Your devices.
2. Select a device > View details > go to IP details.
3. Select View all ISPs.

Troubleshoot with IP visibility

While IP visibility allows you to inspect a device's IP information, use DEX's live analytics to review which Cloudflare data center the device is connected to. When traffic leaves a Cloudflare One Client-connected end-user device, it will hit a Cloudflare data center.

To find which Cloudflare data center a device is connected to:

1. Follow the steps listed in View IP information to find a device's IP information.
2. On the device page, select Colocation & client or find the Client table at the top of the page.
3. In the Client table, find Colocation to review which Cloudflare data center your selected device's outbound (egress) traffic is routed through.
