What are Yahoo's name servers?
Yahoo uses the following name servers (IP addresses are usually not required):
Primary name server: yns1.yahoo.com
Secondary name server: yns2.yahoo.com
NOTE: If you are using our legacy name servers (ns8.san.yahoo.com and ns9.san.yahoo.com), we recommend that you update your name servers to yns1.yahoo.com and yns2.yahoo.com. Using the newest name servers you will notice improved stability.
