Improved
Due to an infrastructure migration, we've updated our static IP ranges. All our customers have already been informed about this change via a set of three emails sent out of the last three weeks.
Here is a short recap:
We've shortened the list of IPv4s per region. The current list of static IPv4s is a subset of the previous list.
The IPv6 range is unchanged.
The new ranges can be fetched from our public API, for instance:
curl https://api.checklyhq.com/v1/static-ips
Please reference our docs on static IP ranges and allowlisting for more info.
If you do not use IP based allowlisting in your infrastructure with Checkly, no action is needed.
If you do use IP based allowlisting, your current firewall(s) will still correctly allow Checkly traffic as the new range is a subset of the old range. However, once we release the superfluous IPv4s back to our hosting provider, these IPv4s could be reused by others and potentially form a threat to you.
Static IP ranges are available to all users on all Checkly plans.
