SPF provides mechanisms, qualifiers, and modifiers to allow domain administrators to specify IP addresses in a highly flexible way.

An SPF record is a TXT record published on the domain starting with "v=spf1". It specifies a list of IP addresses where email messages are allowed to sent on behalf of that domain.

The - qualifier stands for FAIL, i.e., the SPF check fails. The all mechanism in an SPF record matches always.

When combined, -all returns SPF failure for all IPs not matched by prior mechanisms.

Sure. Here is an example SPF record:

v=spf1 include:_spf.example.com -all

This record allows any host with an IP address specified in the SPF record of _spf.example.com to send emails on behalf of a domain. Anything else is rejected with a hard fail.

Generally, you should enforce -all in your SPF record. This gives you maximum SPF security.
