I'm running NCSA Telnet version 2.4 (MacTCP) 3/14/91 which I believe is the
latest available, and when I comment out the "nameserver" entries in the
config.tel file it no longer is able to convert names to numbers, even though
programs *I* wrote that *do* use the MacTCP dns stuff are quite able to lookup
host names at the same time.  Thus I claim that *no* NCSA telnet makes use
of the MacTCP lookup stuff, they ALL do it themselves...

Here is the config.tel in question, my claim is that by removing the last
four lines I can make NCSA telnet not be able to lookup names.
