WordPress.com/Jetpack uses a wide range of IP addresses due to the distributed nature of the service. These IP addresses are also often changing, so keeping a whitelist might not be the best approach; you would need to keep the whitelist updated to make sure Jetpack always works.
Instead, you could use other ways to mitigate XML-RPC attacks without completely blocking access to the file. The most popular hosts out there use tools like fail2ban or ModSecurity, for example. On your end, you can use plugins like this one to disable access to one of the methods used by hackers. You can also use Website Application Firewalls like Sucuri or CloudFlare to block hackers before they even reach your site. And finally, Jetpack itself includes a module that will help against Brute Force attacks.
If you’d rather use IP addresses, you can use the IP ranges mentioned here:
