To add an extra layer of security, many organisations like to block access to their servers to all but a known whitelist of safe IP addresses. If your organisation does this you will need to add an entry in your whitelist to allow QueryTree access to your database servers before using QueryTree to build reports on your data.

QueryTree's database connections will come from the following IP addresses:

191.235.161.78
191.235.161.110
191.235.161.117
191.235.161.5

Updates to this list of IPs will be posted here and emailed out to you.
