The DNS report tool at <http://www.DNSreport.com> now gives a yellow
flag warning for domain without a SPF record.
Do note that this testing tool is quite broken. I gives a spurious "No
glue records" warning on *every* .ORG domain, for instance, and was never
fixed.
The parent servers (TLD1.ULTRADNS.NET and TLD2.ULTRADNS.NET) for the .org
domain indeed do not provide glue records. You can verify this yourself by
running following commands:
dig ns example.org @TLD1.ULTRADNS.NET
dig ns example.org @TLD2.ULTRADNS.NET
and compare this to:
dig ns example.net @A.GTLD-SERVERS.net
So this is the fault of TLD1.ULTRADNS.NET and TLD2.ULTRADNS.NET.
www.DNSreport.com correctly detects this fault.
