I have a client who has a domain name registered with their registrant,
  1. has their own on-prem exchange server
  2. and a website hosted by a 3rd party.  
  3. The website also creates emails when someone makes an online inquiry/feedback.

Today I tried to get the SPF record edited by the registrant, to include the website hosting providers domain and had what equates to an argument via chat over what is/isn't possible.  So I'm here in the court of Experts Exchange to see what your thoughts are.  

Exchange gateway address = 222.222.222.222 (just an example and sorry if its your IP)
Current spf = v=spf1 ip4:222.222.222.222 -all
Website hosting provider = worldsecuresystems.com (their real domain name)

Questions: (and some i know the answer but am starting as if I know nothing in case I am wrong)
  1. Is it possible to add a 2nd mail server to the SPF record?
  2. Can you have a mix of IP's and FQDN's in an spf record
  3. Is the spf syntax v=spf1 ip4:222.222.222.222 Include:worldsecuresystems.com -All
.

Reading resources on Googles own SPF reference talks about this exact scenario, yet openspf.org doesn't (or I haven't yet found)
