Emails from Avectra software bouncing since Migration to Office 365

So what Im being told is that I need to add Avectra email servers to my SPF record.  
Here is the bounce report.  Anybody have a procedure on how to configure this properly.

host smtp.secureserver.net[68.178.213.37] said: 550

I have the addresses and It is 5 of them all in the same subnet do i have to list each one individually?
Added all 5 addresses by FQDN with include:XX.XX  separated by spaces SPF record passes tests without error now we shall see if it actually works

Side note.  I tried using IPV4 addresses DNS wasnt happy about it.
You can also add a subnet in standard CIDR notation:

v=spf1 include:spf.protection.outlook.com ip4:5.6.7.8/27 ip4:1.2.3.4 -all
