如何在不利用其他IP地址的情况下从Ruby获取我的机器的IP地址？ [英] How to get my machine's IP address from Ruby without leveraging from other IP address?

问题描述

我到处搜索，但他们的解决方案需要某种形式的IP地址。
以下是我找到的解决方案。

  require'socket'
 #METHOD 1 
 ip = IPSocket.getaddress（Socket.gethostname）
 put ip 
 
 #METHOD 2 
 host = Socket.gethostname 
 put host 
 
 #METHOD 3（使用Google的地址）
 ip = UDPSocket.open {| s | s.connect（64.233.187.99，1）; s.addr.last} 
 put ip 
 
 #METHOD 4（使用网关地址）
 def local_ip 
 orig，Socket.do_not_reverse_lookup = Socket.do_not_reverse_lookup，true＃暂时关闭反向DNS解析
 
 UDPSocket.open do | s | 
 s.connect'192.168.1.1'，1 
 s.addr.last 
 end 
确保
 Socket.do_not_reverse_lookup = orig 
 end 
 
 ip = local_ip 
 put ip 
  

所有这些都需要IP地址有人。有没有使用别人的IP地址的解决方案？优选地，平台无关。

解决方案

不是您正在寻找的解决方案：

  require'socket'
 
 addr_infos = Socket.ip_address_list 
  

由于一台机器可以有多个接口和多个IP地址，因此该方法返回一个 Addrinfo 。

您可以像这样获取确切的IP地址：

  addr_infos.each do | addr_info | 
 put addr_info.ip_address 
 end 
  

P.S。问题有点陈旧，但显示为Google上的第一项，并且它不包含大多数人正在寻找的解决方案，所以我决定发布它。

<希望它有所帮助。

I have searched everywhere but their solution requires some form of IP address. Here are the solutions i have found.

    require 'socket'
#METHOD 1
    ip = IPSocket.getaddress(Socket.gethostname)
    puts ip 

#METHOD 2
    host = Socket.gethostname
    puts host

#METHOD 3(uses Google's address)
    ip = UDPSocket.open {|s| s.connect("64.233.187.99", 1); s.addr.last}
    puts ip

#METHOD 4(uses gateway address)
    def local_ip
      orig, Socket.do_not_reverse_lookup = Socket.do_not_reverse_lookup, true  # turn off reverse DNS resolution temporarily

      UDPSocket.open do |s|
        s.connect '192.168.1.1', 1
        s.addr.last
      end
    ensure
      Socket.do_not_reverse_lookup = orig
    end

    ip=local_ip
    puts ip

All of them require IP address of someone. Is there a solution that does not use someone else's IP address? Preferably, platform independent.

解决方案

Isn't the solution you are looking for just:

require 'socket'

addr_infos = Socket.ip_address_list

Since a machine can have multiple interfaces and multiple IP Addresses, this method returns an array of Addrinfo.

You can fetch the exact IP addresses like this:

addr_infos.each do |addr_info|
  puts addr_info.ip_address
end

P.S. The question is a bit old, but shows up as the first item on Google and it doesn't contain the solution most people are looking for, so I decided to post it.

Hope it helps.
