Simple Questions Adding IP's

I have purchased an additional 8 IP's xxx.xx.xx.90 through xxx.xx.xx.97.

According to WHM I have to do the following.
Notes: When adding multiple ip address you must used Class C CIDR format or 192.168.0.1-254 format.
Valid Examples: 192.168.4.128/25, 192.168.3.5-10, 192.168.99.55-230

Does that mean to add all IP's at once I would enter into the box Ip(s) to add
xxx.xx.xx.90-97

Then just click do it?? Just want to make sure they are added correctly.

Thanks
