问题 下列四项中,合法的IP地址是(  )。
选项 A.290.220.5 B.206.43.3.78 C.106.53.412.78 D.153.43.82.220.2
答案 B
解析 IP地址是一个32位的二进制数。为方便使用,通常把32位IP地址表示成4组十进制数,每组数字不能大于255,组与组之间用圆点进行分隔,如202.215.208.11。故选B。

Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
