Use IP-addresses to whitelist Zivver in identity provider or firewall

Is it possible to use IP addresses to whitelist Zivver in the identity provider (IdP) or firewall?

Answer

No, it is not possible to use IP addresses to whitelist Zivver in an IdP or firewall.

When users log in with SSO on a laptop, mobile device, or workstation, the SAML request to the IdP uses the IP address of that device.
