What are the current IP address ranges for Zoho Mail?

What are the current IP address ranges for Zoho Mail so that I can add them to my router's whitelist?

So far, I have figured out a couple of them:

136.143.188.0/24

136.143.190.0/24

136.143.191.0/24

Are there any more?

Also, can you identify what Zoho product uses these IP address ranges:

74.201.154.0/23
204.141.32.0/24
204.141.42.0/24

Thank you.
