"dns4.p07.nsone.net" you give me is not a valid host name for the website I bought my domain

I was using “us domain center” to buy my own domain “guangxuanxu.com”, and then I tried to transfer the dns to your server which is ““dns1.p07.nsone.net”” where the ip is "“"”. When I write it down, the "“us domain center” website told me an error that ““dns1.p07.nsone.net”” is an invalid host name. So, what should I do?

Not sure what you’ve tried, but if you were trying to use the nameservers as an A record, that would be incorrect. You might want to contact your domain registrar for help on setting up DNS.
