I work for a AirSatOne. We provide satellite communications to aircraft and we have pilots that use your app but want to block out other web sites to reduce the cost of satellite communications. We would like to have your list of IP addresses or your suggestions to best allow your mobile app to pass through the firewall. We sent an email to you but no response. If you could post it here or if you want to keep them as private as possible you can contact us through the email we sent or through our support email address which is on our web site. Thank you.
We use hundreds of IP addresses dynamically allocated. You have to whitelist domain windy.com
