Actually I want to get site-local or univeral(global) address. Though there is no direct function to get theseaddresses, ipv6_get_lladdr() shows how we can get the other addresses too. > Site-locals are deprecated (http://www.rfc-editor.org/rfc/rfc3879.txt), so I wouldn't think you'll ever find a site-local specific address function. If you do find one, I'd be fairly sure it'd go away. > Thanks, > Mohan Reddy > > On Thu, Mar 04, 2010 at 11:17:39AM -0500, Brian Haley wrote: > > Mohan Reddy wrote: > > > Hi, > > > > > > Is there a function or a way in kernel to get an interface ipv6 address if interface name or net_device object is known?
