post 1.3.1 we added support for IPv6 in the netutils, etc.

None of the individual plugins were affected except for ping.

In netutils the order of the fuctions calls IPv6 resolution first if the 
OS supports IPv6 and then calls IPv4

Perhaps a switch to configure to explicitly disable IPv6 support even if
the OS supports it is needed...
