a "normal" domain-lookup should retreive both IPV4 and IPV6 adresses (multiple)

C:\Users\>nslookup yahoo.com

the dns server you use in your lab may have cached only the first returned adresss from the external dns servers
and presents this to your switch
the command mentioned by @MHM Cisco World gives a more detailed view of the dns-resolving than simple nslookup
