IP Whitelist values for Make.com

Hi Everyone,

I have a form that points to a Make.com Webhook.
They have the option to add IP Restrictions:
“A whitelist of IP addresses delimited by comma. You can use CIDR notation to whitelist a subnet. Leave empty if you don’t want to check the IP address.”

I’ve noticed the odd probing Webhook submission with no data and suspect they’re coming from somewhere other than the website. Can I utilise this whitelist and which IP address/s need to go in there?

Would 75.2.70.75,99.83.190.102 work?

Probably not. When I have to figure out what IP’s a service like this connects from I point the transaction to a web server I control and record the results. That would give you an idea but the better approach would be to reach out to tech support and see if whitelisting is even an option.
