[pfx] SPF format question

Hello If I have a mx server: mx.host.com whose ip is 1.2.3.4. The domain.com who use this mx server may have the following SPF. v=spf1 mx ~all v=spf1 ip4:1.2.3.4 ~all v=spf1 a:mx.host.com ~all v=spf1 mx:domain.com ~all May i know if they mean the same stuff for SPF? Thanks. __
