You can type the domain name of your IPv6 ISP. (Do not enter the domain name for the 
IPv4 ISP here.) For example, if your ISP’s mail server is mail.xxx.yyy.zzz, you would type 
xxx.yyy.zzz as the domain name. If your ISP provided a domain name, type it in this field.

(Optional) Select the Use This Interface ID check box, and specify the interface ID that you
