Problem looking up domain dryfire.com

[Eivind Olsen]

Hello.

I'm seeing some odd problems where BIND (9.10.4-P2) has issues resolving 
getsurfed.com. This is when using the "510 Software Group" BIND 9.10 for 
RHEL/CentOS/Fedora.

I can do manual lookups of the domain with "dig" and point it to their 
servers (dns0.getsurfed.com, dns1.getsurfed.com) but it fails for me if 
I go through my BIND installation.

The named.run log contains lines like this:

16-Aug-2016 10:48:40.693 lame-servers: info: 17 unexpected RCODE 
resolving 'dryfire.com/NS/IN': 213.162.97.178#53
16-Aug-2016 10:48:40.749 lame-servers: info: 17 unexpected RCODE 
resolving 'dryfire.com/NS/IN': 213.162.97.177#53

A search for "17 unexpected RCODE" seems to indicate this might be 
caused by incompatibility between SIT/DNS cookies and older versions of 
NSD. Is this also what's happening in my case here?
