# C1 network requirements

> IP addresses and hostnames required for C1 access. Add these to your firewall and proxy allowlists.

If your organization restricts outbound traffic by source IP, add the following C1 egress IP addresses to your firewall or application allowlist. This ensures that C1's cloud-hosted connectors and functions can reach your systems.

<Note>
  These addresses apply only to **cloud-hosted** connectors and functions. If you self-host connectors in your own environment, outbound traffic originates from your own infrastructure and these IPs do not apply.
</Note>

## Connector egress IPs

Cloud-hosted connectors use the following IP addresses for outbound traffic to your integrated systems (such as syncing data and provisioning accounts):

```
35.85.212.195
35.82.205.32
52.33.197.26
54.68.132.142
```

## Function egress IPs

[Functions](/product/admin/functions) use the following IP addresses for outbound traffic:

```
54.214.48.9
54.212.53.161
```

## C1 hostnames

If your organization uses a web proxy, content filter, or firewall that restricts outbound HTTPS traffic, add the following hostnames to your allowlist. This ensures that users can access the C1 web application and that AI (MCP) traffic flows correctly.

| Hostname                         | Port | Purpose                                                   |
| -------------------------------- | ---- | --------------------------------------------------------- |
| `assets.ctr1.net`                | 443  | CDN — JavaScript, CSS, and images for the web application |
| `<tenantName>.conductor.one`     | 443  | Web application and API endpoints                         |
| `<tenantName>-mcp.conductor.one` | 443  | AI traffic (MCP protocol)                                 |
| `accounts.conductor.one`         | 443  | Login and SSO flow                                        |

Replace `<tenantName>` with your organization's C1 tenant name.

## Staying informed of changes

IP addresses are subject to change. To stay informed:
