Afternoon, all, 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. I know the list exists, I saw it years ago and someone quoted such a list on this NANOG mailing list a day or two ago. So, if someone would be kind enough to mail me a link to this most essential of services, I would be grateful. I appologize in advance for poluting the NANOG list with yet more actual operational questions. Curt- Howland@ConXioN.com
Curt,

Try a dig on the root servers. Or see attached. You will see "." has I-M up whereas com stops at H.
