Thanks !

Your mirror http://mirrors.dgut.edu.cn/centos/ has been added to the mirrors DB It will be listed as a public mirror (and on https://mirror-status.centos.org / https://www.centos.org/download/mirrors/ ) in the following minutes/hours. Your IP address[es] (219.222.181.16 27.39.221.250 ) has/have been added in the ACL and so you should be able to rsync from msync.centos.org in the next ~10min

Kind Regards,

PS: the IPv4 address you asked to be added in the ACL is really different from the A record (allowed too)
