[dns-operations] hichina.com technical contact

[Petr Špaček]

Hello dns-operations,

could anyone share a technical contact for hichina.com DNS?

I would like to report a huge cluster of broken domains but the e-mail
address from SOA is useless:

> <hostmaster at hichina.com>: host mxn.mxhichina.com[205.204.101.145] said: 554
>     RCPT (hostmaster at hichina.com) dosn't exist (in reply to RCPT TO command)

Thank you for any advice!
