namesilo 的域名可以直接跳转到别的 url 吗

用自己的空间或者 VPS 做 301 跳转吧

是cname的意思吗？

跳转需要web server的支持，不是域名层面上的东西。

设置一下DNS就可以了啊

@gDD 4楼说的对。
Permanent Forward (301): Selecting this option will redirect web traffic using a 301 permanent redirection. This is the recommended option and should be used for domains that will always forward traffic and for which there are no plans to develop a site specifically for the domain.(People will see the target domain that's being forwarded to in the address bar.)
Temporary Forward (302): Selecting this option will redirect web traffic using a 302 found redirection. This option should be used for domains that are only temporarily redirecting traffic elsewhere, and for which there are plans to develop a site for that domain.(People will see the target domain that's being forwarded to in the address bar.)
Cloaked Forward: Selecting this option will generate a frameset displaying the forwarded site as though it were redirected. The main benefits to this option are that your domain will always appear in the user's address bar, and being able to provide your own META information.
