是否有类似于此代码的命令可打印出存储在此变量中的IP的MAC地址或“哈希码”?我做了一些研究,看起来这可能是一项非常复杂甚至不可能完成的任务。但我认为值得一问。(编辑:我搜索的任何IP都是我的网络的内部IP )。
IPAddress addr = IPAddress.Parse(inputIP); //uses the input IP data into the addr variable to get host
IPHostEntry entry = Dns.GetHostEntry(addr); //Get hostname
我有几个关于IP地址的问题。
The public IP for a company is 190.28.0.0.
a)This is a class B address, right? CIDR value is /16?
b)If the company wants to have 8 subnets, how do I find the subnet mask?
c)What is the maximum number of hosts?
d)What are the IP ranges for the 8 subnets?
我试图在python脚本中获取原始的客户端ip地址。客户端使用代理连接到web服务器。下面的代码总是返回代理ip地址。我测试了所有env变量,HTTP_CLIENT_IP和HTTP_X_FORWARDED_FOR都没有返回。还有其他方法来获取代理背后的客户端ip吗?就像我可以在python中读取http头一样?
ipaddr = (getenv("HTTP_CLIENT_IP") or
getenv("HTTP_X_FORWARDED_FOR") or
getenv("REMOTE_ADDR") or
"UNKNOWN")
我想要所有的ip都属于一个域,例如google.com,我最近看了一下,。所以,我要做的是这样:
<?php
// clientIp() will iterate from 1.1.1.1 to 255.255.255.255
App::uses('IP2LocationCore', 'IP2Location.Model');
$IP2Location = new IP2LocationCore();
$record = $IP2Location->get($this->request->clientIp());
if(strcmp($
有个方法-
public static String getHostByAddr(byte[] addr) throws UnknownHostException {
Name name = ReverseMap.fromAddress(InetAddress.getByAddress(addr));
final String[] servers = new String[] {"208.67.220.220", "208.67.222.222"};
final Resolver res = new ExtendedResolver(

嗨伙计们,
长话短说,我需要限制访问我的网站的某一部分,基于一个动态IP源地址,不时变化。从历史上看,我只是在htaccess中添加了以下内容.
order deny,allow
deny from all
# allow my dynamic IP address
allow from <dynamic ip>
但问题是,每次IP更改时,我都必须手动进行更改。
理想情况下,我想指定主机名.类似于:
order deny,allow
deny from all
# allow my host
allow from hostname.whatev
