Does Identity-Aware Proxy re-use an IP address for simultaneous users?

Question

When using Identity Aware Proxy to tunnel SSH traffic to a VM, the incoming traffic comes from an IP address in the range: 35.235.240.0/20.

If more than user connects to a VM at the same time, does IAP reuse an IP address, or does it guarantee that each session will have a unique IP address associated to it?

For instance, if 5 users in the machine at once who themselves, would they possibly see the same IP in this output:

foo_user   pts/0        2021-01-27 18:18 (35.235.241.18)

Answer 1

Got an answer elsewhere -- there is no guarantee that different users will connect via different IP addresses. It could be the case that simultaneous users tunneled in using the same IP address from the 35.235.240.0/20.
