@yctercero I checked the 7.17 value list docs, and didn't find info on list size limits.

Is the following information still applicable to value lists that are created in 7.x or does it only apply to 8.x? If it doesn't apply to 7.x, I'll close this PR since it's no longer necessary.

When you create a value list for a rule exception, be mindful of the list's size and data type. All rule types support value list exceptions, but extremely large lists or certain data types have limitations.

Custom query, machine learning, and indicator match rules support the following value list types and sizes:

• Keywords or IP addresses list types with more than 65,536 values
• IP ranges list type with over 200 dash notation values (for example, 127.0.0.1-127.0.0.4 is one value) or more than 65,536 CIDR notation values

@nastasha-solomon let me know if I can help with this one. Happy to quickly hop on a zoom to determine the changes needed.

@yctercero and @e40pud the updated docs are ready for review here. Step one already lists the supported file types, so I just added the file size limit to the note under it.

Thank you!
