NTP server 224.0.1.1

Hi,

is 224.0.1.1 an internal ip for unity ? Looks I cannot set it as my NTP server.

root@xxxx:/root> uemcli -d 10.1.1.xxx -u Local/admin -p  xxx /net/ntp/server create -server 224.0.1.1
Storage system address: 10.1.1.xxx
Storage system port: 443
HTTPS connection

Operation failed. Error code: 0x3400004
The specified IP address is not supported or the address is reserved for internal use. (Error Code:0x3400004)

Regards,

Vivek
