AAAA type query invalidates A records in name server cache

[mailsecurity]

All,

anyone experiencing the same behavior?

Seen on

BIND 9.5.2-P2 and BIND 9.8.0-P4

 

ns11:~ # nslookup -querytype=A xserv.ins.dell.com.

.

Non-authoritative answer:

Name:   xserv.ins.dell.com

Address: 143.166.148.118

 

All ok.

 

ns11:~ # nslookup -querytype= xserv.ins.dell.com.

.

** server can't find xserv.ins.dell.com.: NXDOMAIN

 

Now even the A queries fail.

ns11:~ # nslookup -querytype=A xserv.ins.dell.com.

.

** server can't find xserv.ins.dell.com.: NXDOMAIN

 

Keeps failing until TTL timeout or rndc flushname xserv.ins.dell.com.

 

ns11:~ # nslookup -querytype=A xserv.ins.dell.com.

.

Non-authoritative answer:

Name:   xserv.ins.dell.com

Address: 143.166.148.118

 

Thanks,

Patrick
