💡 Keep in mind, with the exception of the Webex Events Production Studio, we don't supply allowlist IP addresses because most addresses Webex Events uses are dynamic.

Firewalls and web filters are common protections for many businesses and organizations. Networks protected by these measures may only allow outbound connections to certain domains, which could keep some Webex Events (formerly Socio) products and features from working.

We want to make sure that your attendees have the best experience possible, so we've compiled this list of email addresses and URLs so attendees and network admins can add allowlist exceptions.

Webex Events email addresses

Password reset emails, registration confirmation emails, and custom button response emails all use these addresses:

Webex Events (Socio) domains

Webex Events Production Studio IP addresses

When using the Webex Events Production Studio, allowlist the following IP range and ports:

  • IP Address Range: -

  • UDP Port Range: 50000 - 60000

  • TCP Port: 7881

  • TURN UDP port: 3478

💡 Keep in mind, you may only allow UDP Port Range, TURN UDP port, or TCP port. For the best audio and video experience, we encourage allowlisting the UDP Port Range or TURN UDP port.

Slido Studio player URLs

The Slido Studio is a modified version of the Webex Events Production Studio. If you're using the Slido Studio, add all the IP addresses and ports noted above in addition to these URLs:



💡 Keep in mind, the Slido Studio is currently in early-access Beta. For more information, contact Slido.

Third-party domains

  • - We use Intercom for our Live Chat software to provide tech support and the knowledge base you're reading right now.

  • - We use Segment to collect analytics data that we provide to the event organizer.

  • and - We use Google’s Firebase for authentication, chat database, and database for real-time functionality.

    • *

      💡 Keep in mind, for stricter Firebase permission, allowlist only the Webex Events App (Socio) subdomain: If you're using a Branded App, contact our Support team for your app's unique subdomain.

💡 Keep in mind, Webex Events strives to promote inclusivity, including in the words we use. This is why we use the term 'allowlist' instead of 'whitelist' or 'white list', which were previously common in the IT industry.
