If you are using an existing domain with your new hosting account, you will need to update the nameservers to point to the nameservers listed below.

Nameserver 1: ns1.x90x.net 31.170.163.241
Nameserver 2: ns2.x90x.net 64.191.115.234
Nameserver 3: ns3.x90x.net 173.192.183.247
Nameserver 4: ns4.x90x.net 31.170.164.249

请问tk域名这样解析后为什么会出现错误呢？
