汉英对照:
Chinese-English Translation:

内网有自己的 IP 号段,不会和互联网号段冲突,不能拥有外网 IP,由个人或者小群体使用。外网 IP 用于公司企业,学校等机构。内网电脑连接外网需要一个统一出口,而外网则不需要。

The internal network has its own IP number segment, which will not conflict with the Internet number segment, and cannot have the external IP, which is used by individuals or small groups. Internet IP is used in companies, schools and other institutions. Intranet computers need a unified outlet to connect to the Internet, while the Internet does not.

内网和外网是我们生活中经常会接触到的,比如大学校园里就多采用内网。那么这两者有什么区别呢?

Intranet and extranet are often contacted in our life, for example, intranet is often used in university campus. So what’s the difference between the two?

内网和外网的不同

Difference between intranet and Extranet

1、ip 地址设置的区别,一般内网有自己的 IP 号段,从路由器以下开始的,通常是 192 开头的 IP 号段,它不会和互联网号段冲突。一般是不能拥有外网 IP 的,因为个人或者小群体用外网是一种资源浪费,所以一般都是通过内网去上网的,外网 IP 一般都是用于公司企业等机构的。

1、 The difference of IP address setting is that the internal network generally has its own IP number segment. Starting from below the router, the IP number segment usually starts from 192. It will not conflict with the Internet number segment. Generally, you can’t have Internet IP. Because it’s a waste of resources for individuals or small groups to use the Internet, they usually use the Internet through the intranet. The Internet IP is generally used for companies, enterprises and other institutions.

2、连接网络的区别,内网电脑连接外网需要一个统一出口,可能被限制一些不必要的访问,而外网就是不经路由器或交换机就可以上网的网络,可以直接被外界所访问到,无需经任何设备,直接连接电脑。

2. The difference between connecting networks, the internal network computers need a unified outlet to connect to the external network, which may be restricted to some unnecessary access, while the external network is a network that can access the Internet without router or switch, and can be directly accessed by the outside world, without any equipment, directly connected to the computer.

3、安全性的区别,内网相对外网会多一层安全防火墙,相对来说抵御来自外网的攻击能力会好一些;但内网的不足之处在于,可能会遭到来自内部的攻击;并且因为要共享带宽,相对网速可能会慢些。

3. The difference of security is that there will be a layer of security firewall in the internal network compared with the external network, and the ability to resist attacks from the external network will be better; however, the disadvantage of the internal network is that it may be attacked from the internal; and because of the need to share bandwidth, the relative network speed may be slower.

4、范围大小的区别,内网相对于外网来说,范围更小,可以是一个家庭、一个学校或者一个部门。有一定的地理范围大小。而外网则要广泛得多。

4. The difference of scope size: compared with the external network, the internal network has a smaller scope, which can be a family, a school or a department. There is a certain geographical scope. The Internet is much broader.

总的来说,内网和外网主要有四点区别,分别是 IP 地址、连接方式、安全性和范围大小的区别。

Generally speaking, there are four main differences between the internal network and the external network, which are IP address, connection mode, security and range size.
