Using FogBugz On Demand? We've recently rolled out a new sidebar as part of taking FogBugz forward. Please see this article for details on what's new, what's changed, and where you can find all your favorite things.

This list contains our public IP addresses. You may add these to your networking equipment (hardware or software) to whitelist our FogBugz and Kiln On Demand environment. This is helpful for receiving email notifications, retrieving  email via POP3 or IMAP if you’re using FogBugz Mailboxes, using the On Demand service itself, or using other outbound services like URL Trigger.

Outgoing email (like FogBugz email notifications) will also originate from these subnets, which may be useful for you to enter into your spam filter.


This website is useful to get a list of all the IP addresses based on the subnet range identified above:

You can also include our SPF records here.
