If you use "?" as a modifier to ranges within your SPF record then it will match (and prevent further processing) but it will not count as a pass towards DMARC. Some people see this as being preferable to eschewing having any SPF record at all because (a) Google (unwisely in my view) say you should have one if you want to deliver to them and (b) some small mailbox providers believe in the value of SPF to do early stage filtering of mailflows and may penalise your domain for not having any SPF at all.
