Einai auto IPv6??? Pws tou hr8e tou traceroute na to xrhsimopoihsei? Apo 
thn manual page, blepw auto:

-6, -4 Explicitly force IPv4 or IPv6 traceouting. By default, the 
program will try to resolve the name given, and choose the appropriate 
protocol automatically.  If resolving a host name returns both IPv4 and 
IPv6 addresses, traceroute will use IPv4. Invoking the program as 
traceroute6 is the same as using the -6 option.

Omws, an paw na to kanw resolve:
linapp:/tmp # dig ftp.duth.gr
