We are seeing IPv6 DNS queries being sent on SLES servers.
We have disabled ipv6 module from the kernel, and are noticing this behaviour only on some applicaitons like wget, telnet

A similar issue can be found here => http://forums.novell.com/novell-prod...aaaa-ipv6.html

======
Verified that IPv6 parameter is disabled.
