1	picasa.google.ru.	.	(g,e,i,j,l,f,a,d,b,h,c,m,k).root-servers.net.
2	picasa.google.ru.	ru.	(a,f,b,e,d).dns.ripn.net.

7	www2.l.google.com.	google.com.	(ns3,ns2,ns1,ns4).google.com.

We pick g.root-servers.net, one of the 13 root servers (1), and ask it about picasa.google.ru and learn that ru is delegated to five name servers (2), so we ask a.dns.ripn.net where we learn that google.ru is delegated to four name servers, including ns1.google.com (3), so we ask that one where we see a CNAME from picasa.google.ru to picasa.google.com, so we have to start all over again. We pick f.root-servers.net, one of the 13 root servers (4), and ask it about picasa.google.com and learn that com is delegated to 13 name servers (5), so we ask c.gtld-servers.net where we learn that google.com is delegated to four name servers, including ns4.google.com (6), so we ask that one and see a second CNAME from picasa.google.com to www2.l.google.com. We start over for the third time and we already know that ns3.google.com is authoritative for google.com (7) and ask it about www2.l.google.com and get the following answer:
