Whitelist SonarCloud IPs for webhook server

[Colin]

Hey there.

Take a look at the answer here:

New Webhook IP Address

Hi @SimonyanG, By design, the IP addresses SonarCloud is invoking webhooks from will change with time (e.g. with the service auto-scaling). We can’t commit to a specific IP range, so therefore indeed, it is not realistic to use firewalls to protect webhooks targets. Instead, to protect your endpoint, the correct solution is to use a secret, as explained in the webhooks documentation page.
