Checkly now supports both IPv4 and IPv6, also called dual stack. This means that we can reach both IPv4 and IPv6 addresses from our check runtime.

Note that for most workloads (API checks, browser checks, etc.) the IPv6 stack is automatically preferred over IPv4 if available. This means that if your endpoint is reachable over IPv6, we will use that. If not, we will fall back to IPv4.

For Browser checks, you can instruct the Chrome instance to actually prefer IPv4. Have a look at our docs for a code example on how to achieve that.

Note that browser checks still using Puppeteer are not running on our dual stack infra as we are deprecating Puppeteer support.

IPv6 is automatically enabled and available on all plans.
