How/Where can we confirm if CA ASM monitoring stations IPs are fixed for a city?

Current release of App Synthetic Monitor

  For CA ASM monitoring stations, all Stations can be checked on below URL:

  https://asm.ca.com/en/products/monitoring-stations

  Once the Station is set, the IPs are static. But this can change without prior notice. Changes are usually communicated using the notification email (added stations, replaced stations etc.).  The list of IPs is available to logged in users via the page mentioned above.
