java中实现比对ip地址是否在一个ip地址段中
一、假如一个ip段192.168.0.1-192.168.0.255
String ipd = "192.168.0.1-192.168.0.255";
二、目标ip为192.168.0.125
String userip = "192.168.0.125";
三、实现
??????????????? boolean flag = false;
??? ??? ??? ??? String[] ipdd = ipd.split("-");
??? ??? ??? ??? String ipbg = ipdd[0].replace(".", "");
??? ??? ??? ??? String ipend = ipadd[1].replace(".", "");
??? ??? ??? ??? if (Long.parseLong(userip) >= Long.parseLong(ipbg)
??? ??? ??? ??? ??? ??? && Long.parseLong(userip) <= Long.parseLong(ipend)) {
??? ??? ??? ??? ??? flag = true;
??? ??? ??? ??? }
四、判断flag就可以了。
