I have Netware server 6.5 sp

I would like to know if with the "ping" command on the server it's possible
to ping
a URL (not a ip adresse) like: www.yahoo.fr , ftp.symantec.com
Because with my serveur i can ping the ip adresse of yahoo, symantec but
it's not possible the URL name.

I can to do the nslookup of www.yahoo.fr, of ftp.symantec.com , ....
I can to do the nslookup of the ip adress too

It's normal if I can't to do the URL ping?

I use the DNS of my provider.

Thank you,
