Strange, todays active domain is: apparty.bid

apparty.bid descriptive text "v=spf1 ip4: -all"

We do check SPF, so why did this email pass? Is 'ip4:' equivalent to
the whole IPv4 space?

apparty.bid has SOA record dns1.registrar-servers.com.
hostmaster.registrar-servers.com. 2017083103 43200 3600 604800 3601

The SOA has been updated today. Was the SPF entry added after the
emails were sent? (Last emails passed at 15:03 UTC+2)

And no, the domain does not seem to be parked, the spamversized site
is still up (some spaces inserted to avoid triggering URI blacklists)

http://too.

Redirecting to a site which according to WOT is being spamvertized
since 2014.
