I'd go for a bug in the documentation. Names ending with a dot don't get the search list appended to the name on a lookup failure. Think about it.. the trailing dot is the root of the DNS tree. I wouldn't make sense to add anything after that. > To my > knowledge, DNS domains support "relative" names (e.g. "www.example.com") > as well as "absolute" names (e.g. "www.example.com." - with the trailing > dot).

You can always put the trailing dot in there yourself - eg ping foo.home. if you don't want the search list appended on a lookup failure. Lee
