取决于您的提供商，大多数提供商使用的DHCP会在几周内重置一次，为您提供不同的IP地址。但有些则不然，大部分时间都是特殊的互联网为企业提供。







我有一个需要识别的网站用户从他们正在进入网站的计算机获取的信息。是否可以这样做？



是的，你可以这样做。你可以使用他们的ip-adresses或使用cookies ...

does my computer have the same ip address all the time, or does it change it dynamically?

Depence on your provider, most providers use a DHCP that will reset once a few weeks, giving you a different IP adress. But some don't, most of the time this is a special internet-offer for businesses.



I have a web site which need to identify the users from the information derived from the computer they are looging into the site. Is it posssible to do this?

Yes, you can do this. You can use their ip-adresses or use cookies...

要添加到其他响应，如果你没有指定 - 而且大多数人没有 - 那么ISP将分配一个动态IP地址 - 但这不是您的PC的IP。它是您的调制解调器的IP。如果您有许多人共享相同的互联网连接（工作场所正常）然后他们将拥有相同的IP，具有不同的子网地址。所以我可以登录并拥有与坐在我旁边的人相同的IP。



每当重新启动调制解调器时，动态IP地址将被更新。所以我可以登录你的网站，关闭我的调制解调器然后再打开一个新IP。

To add to the other responses, if you do not specify - and most people don't - then the ISP will assign a dynamic IP address - but that isn't the IP of your PC. It is the IP of your modem. If you have a number of people sharing the same internet connection (normal for a work place) then they will all have the same IP, with a different subnet address. So I could log in and have the same IP as the guy sitting next to me.

The dynamic IP address will be renewed whenever the modem is re-started. So I could log into your site, turn my modem off and on again, and come in on a new IP.

取决于您的ISP和您的设置。



您可以选择拥有动态IP，（推荐）或静态IP。 />


每个人都有自己喜欢的选择。

Depends on your ISP and your settings.

You can have the option to have a dynamic IP, (recommended), or a static one.

Everyone has their preferred option.
