互联网是一个由不相关的计算机组成的世界性网络,只有同意合并一套规则或协议,才能成功地进行通信。互联网最基本的原则之一是互联网协议(IP)地址。

Internet Protocol (IP) addresses are one of the most basic tenets of the Internet.

IP地址是指分配给Internet上每台计算机的唯一编号。IP号码被称为“地址”,因为它与家庭地址的用途相同——它允许通过数字方案定位互联网上的每台机器。域名,如www.wisegek。com,也映射到数字IP地址。在这种情况下,它是69.56。209.194.

Each computer that is connected to the internet has a unique IP address that can be used to identify users and their location.

大多数人都熟悉通过互联网服务提供商(ISP)获得IP地址的想法。ISP可能提供动态或静态地址。静态地址是一个永久地址,而动态地址随着每个新的Internet会话而变化。每个ISP都有一个唯一的可用IP地址范围。

除非安排静态IP地址,否则动态地址将在登录过程中自动分配,并将一直持续到有意终止或禁用连接为止。再次登录后,将分配一个新的。在每种情况下,Internet上的计算机都将接受请求并将数据返回到您计算机的当前IP地址。当浏览器请求网页、邮件和其他在线数据时,此IP号码将成为“信封”上“返回地址”的一部分。

IP地址可以通过请求ISP的日志记录映射回特定用户。例如,在非法在线行为的情况下,执法部门可能会传唤ISP,要求其提供客户的姓名、地址和其他个人信息,该客户被分配了与所涉犯罪活动相关的特定IP地址。一些ISP不需要传票。

网站通常通过IP地址跟踪访问者,以查看感兴趣的页面。当注册和cookie开始使用时,身份可以链接到地址。cookie可以“告诉站点”用户是谁,尽管IP地址在变化。根据访问者提供的信息,网站可能有真实或虚假的信息。

虽然互联网可能感觉匿名,但默认情况下它不是匿名环境。IP地址是指向最终用户的第一个也是最后一个链接。为了匿名冲浪,许多人选择使用网站“隐藏”自己的地址,用自己的IP地址代替用户的IP地址。提供匿名冲浪的网站在充当中间人的同时,将用户的地址隐藏在互联网之外。当然,提供此服务的网站仍然有最终用户IP地址的记录。

Unless a static IP address is set up, a dynamic address is automatically assigned in the login process and will persist until the connection is intentionally ended or disabled.
