In order for a blog or forum to use Akismet to check spam, it needs to be able to make outgoing TCP connections to servers at Akismet.com. If your network normally blocks outgoing connections from your public web servers, you’ll need to add a firewall rule permitting connections to Akismet.
If your security filters allow exceptions based on hostnames, you should permit connections on port 80 to these:
Most Akismet API calls will be made to a host name of the form
api_key is an alphanumeric string that is different for each web site owner.
If your security filters only allow IP-based rules, please refer to the Akismet Hosting FAQ for the list of current IP addresses.
Akismet Specific System Requirements
Akismet is a spam filtering service. It’s most commonly used with WordPress, but is often used with other blog platforms, forum applications, contact forms and similar web apps. It’s a centralized service, so TCP connectivity to servers at Akismet.com is required for it to work.
System requirements for the WordPress plugin are the same as for WordPress, plus:
gethostbynamelfunctions must not be disabled (they are enabled by default in PHP).
- TCP connectivity to akismet.com
System requirements for other Akismet plugins and implementations vary, but TCP connectivity is always required.

Whitelist all communications between WordPress.com and Jetpack
Jetpack, much like other plugins, services, and apps like the mobile apps, relies on the XML-RPC file to communicate with WordPress.com.
If you’d prefer to use a whitelist, you’ll need to whitelist those IP ranges:
Using Jetpack with Cloudflare and/or Sucuri
By default, Cloudflare and Jetpack should require no additional configuration to operate together, if there are not any additional security configuration specified with Cloudflare.
If you are using Cloudflare (with additional security rules) or Sucuri, these are the ranges they accept:

Important: These IP addresses are subject to change. If you are writing IP-based firewall rules, you’ll need to update those rules any time the addresses change. We also have machine-readable versions of these IP ranges in JSON and plain text format that you can use to automate configuration changes on your systems.
If you are using Cloudflare they also support only allowing traffic coming from servers with an specific AS number, in that case you can whitelist the AS number
