Hi,

But in any case, these would still point to the Verisign servers for resolving .com names.  It does not really matter where the roots are in this particular issue.  The only relevance of the root servers if for identifying where to find .com or any of the other top levels. I don't assume that K will be redefining the location of the .com server.
