Curt,
After reading the commentaries about top level domain servers
and their reality or mythical status, I went on a search of a
list of the present "." and top-level servers.Well, no luck. I searched the RFC's, resource pages, IETF.org
and IANA.org pages, nada. I tried to RTFM, but couldn't find
the FM.
Try a dig on the root servers.
Or see attached.
You will see "." has I-M up whereas com stops at H.
