Those issues like DNS resolving and EDNS at the end of your scan, were 
not because there are errors, but because the scanner got IP banned part 
way through generating the report, causing my DNS to stop replying. My 
server IP bans unnecessary scanning because generally those are hackers 
and people up to go good. But for argument sake i un-banned the IP's and 
re-ran the report for you to nit pick at:

And your point? Because im using the same server for both DNS that 
proves what? That everything i said is wrong? If what i said is wrong 
how bout debate that on its own merits instead of resorting to this kind 
of childishness. Hey look, i can run your domain too, omg you also have 
warnings. So by your logic we are both equally what? Wrong?

My warning is ONLY for sharing DNS servers on the same /24, nothing 
about actually being misconfigured unlike your server:

    No response from nameserver(s) on PTR query 
(113.98.183.185.in-addr.arpa.).
    No response from nameserver(s) on PTR query 
(3.5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.c.5.1.0.5.0.0.0.0.0.d.d.4.0.a.2.ip6.arpa.).
    Nameserver ns1.ausics.net/45.58.49.89 allow zone transfer using AXFR.

Oops. How does that saying go about stones and glass houses.
