I'm not advocating it, just pointing out the inconsistency that is exposed by this practice. On the one hand, we've got different servers returning different kinds of data for domains under com/net, depending on whether they are using a workaround or not (some give A or NODATA, others give NXDOMAIN). The namespace is inconsistent. Meanwhile, the argument against multiple roots (at the high level) is that the namespace becomes inconsistent. I don't see any substantitive difference at the high level of the debate. Sure there are other substantitive differences -- workarounds are contained to an administrative scope (until you consider the impact of cached glue data, anyway) -- but not at the high level. This is something VeriSign has invited. Just like when they post queries about fixing mail servers that were broken by their own deployment. -- Eric A.
