Enterprise customers often have split tunnel VPNs or proxies (with PAC configs) where part of the traffic may go through a VPN and another part goes directly. So for example a customer admin might configure an app that does email and webRTC so that the real time traffic (media and the associated signalling) goes directly and the email traffic goes via some TLS intercepting proxy for some compliance reason or DLP. This can result in one application having multiple public IPs for different network requests, even while they are on one internal network (not even jumping between networks like you say). That isnt something that the application author can control, it's the customer admin that decides to do that.
