Errors in tracepath using ittrn01

I see a strange '???' host in tracepath to grenvil.ws.cs.unibo.it:
1. gw-611.trn-01.it.sixxs.net 2. if-1-12.charleston.CBQ.TRN.ipv6.ITgate.net 3. if-0-1.scooby-monster.core.TRN.ipv6.ITgate.net 4. if-4-0.tango.core.MIL2.ipv6.ITgate.net 5. if-2-0.mambo.core.MIL1.ipv6.ITgate.net 6. ??? 7. rt-mi2-rt1-mi1.mi1.garr.net 8. rt1-mi1-rt1-bo1-l2.bo1.garr.net 9. 2001:760:ffff:201::16 10. 2001:760:2e00:affe::3 11. 2001:760:2e00:afff::2 12. 2001:760:2e00:f004:218:8bff:fe0c:9728
There is no packet loss, but that unknown host between ITgate and GARR looks like the source of the problems I have connecting to that host. What that '???' could mean? (path produced by mtr)
