You are doing an nslookup on the domain
name, which you do not use with your browser.
I do want to access google.com and i can't.
if you mean the name server:
>nslookup 12.127.16.83
Server: tmtu.mt.rs.els-gms.att.net
Address: 12.127.16.83
Name: tmtu.mt.rs.els-gms.att.net
Address: 12.127.16.83
Furthermore, I can't access the google.com using its ip addr in my browser.
