It's a chain of CNAME pointers. If you look at the names on the right-hand side of the lines with "CNAME" in them, they are the same as the left-hand name on the following line, until you get to the final step where the right-hand name leads to two A records (which then hold the IP addresses you wanted).

Are this names of different servers? Or same one?

Also, some other DNS server returns in its answer only 3 CNAMEs (and not this whole list) and I see in wireshark for the 3rd CMANE :

nokia.supl.svc.ovi.com.glb.as1248.net: type A, class IN, addr 127.0.0.1

(So i get localhost as my query result and can not establish connection)

How can that be? Why does it return only 3 and not the whole list, like i got when i did 'dig' command?

Thanks
