RE: which DNS does SPF record belong in + macro question

So forget their DNS servers and go to zoneedit.com and do your own. 
It's easy, the only thing you can't do is "_SPF" since they don't allow 
the "_".

Wait, you're paying them for DNS hosting, but they refuse to create DNS
records for you?  It should be fairly simple:  "I want the following TXT
record for mydomain.com: v=spf1 blah blah blah" and they should
create it,
whether they "support" SPF or not.

If they don't want to add records for interland.com, that's their
business,
but they should be willing to add any DNS record you want for
yourdomain.com if they host it for you.

They _should_ be willing, but they are not.  They support user control of A,
MX and CNAME records and that's it.  They are a large hosting service, and
their attitude is pretty much, "My way or the highway".

Incidentally, you only need to know Interland's IP addresses if you use
them to send outgoing mail.  If you send mail through abc.net, and use
xyz.com to host your DNS record, you only need to know abc.net's outgoing
mail servers.  Then you build an SPF record with that info, and
ask xyz.com
to add it as a TXT record for yourdomain.com.

Interland's outgoing MX's are distinct from their web hosting clusters.  All
their MX's, incoming, outgoing and transfer, operate from the
registeredsite.com/14 netblock, not from anything related to the
Interland.com IP addresses.  A /14 netblock is so big that it is at best a
weak test for forgeries.  That is why I was looking for a way to narrow down
the range without knowing the actual CIDR address range.  From experience, I
can take an educated guess as the /24 they use for outgoing MX's, but they
won't validate it so I can't depend on it.
