03 Defanging an IP Address
题目 Given a valid (IPv4) IP address, return a defanged version of that IP address. A defanged IP address replaces every period “.” with “[.]”. Example 1: Input: address = “1.1.1.1” Output: “1[.]1[.]1[.]1” Example 2: Input: address = “255.100.50.0 ” Output: “255[.]100[.]50[.]0” Constraints: The given address is a valid IPv4 address. "[.]".join(address.split(".")); //基于正则表达式 return address.replaceAll("\\

mysql报错 IP address xxxx could not be resolved: Name or service not known错误解决
一 原因 mysql日志显示[Warning] IP address 'xxxx' could not be resolved: Name or service not known 那是因为mysql默认会反向解析 DNS，对于访问者Mysql不会判断是hosts还是ip都会进行dns反向解析，频繁地查询数据库和权限检查，这大大增加了数据库的压力，导致数据库连接缓慢，严重的时候甚至死机，出现“连接数据库时出错”等字样

The Address of an Array
The name of the array is interpreted ad the address of the first element of an array,whereas applying the address operator yields the address of the whole array. result of output is 20 cout<<tell<<endl; //displays &tell[0] cout<<&tell<<endl; //displays address of a 2-byte block of memory,whereas &tell is the address of a 20-byte block of memory. So the expression tell+1 adds 2 to the address value,whereas &tell+1 adds 20 to the address value.

Network Address Translation
With Network Address Translation (NAT), IP addresses are mapped from one realm to another, in an attempt The NAT box is assigned two globally unique IP addresses (145.67.8.3 and 145.67.8.4) for address translation For IP packets on the return path, a similar address translation is required. For this project, we assume that the NAT box has a globally unique IP address for each host in the private and option name IP_NAT_SET.
