首先,我们来看一下如何使用ip命令来进行IP地址的转换。在红帽系统上,可以使用ip命令来添加、删除和修改IP地址。比如,要给eth0网卡添加一个IP地址为192.168.1.100的地址,可以使用以下命令: ```bash ip addr add 192.168.1.100/24 dev eth0 ``` 其中,`add`表示添加一个IP地址,`192.168.1.100/24`表示要添加的I...

* a) gateway can be actually local interface address, so that gatewayed route is direct. 网关可以是本地接口上的地址,所以目的网络是直连的。 * b) gateway must be on-link address, possibly described not by an ifaddr, but also by a direct route. ...

Now that you know how to checkIP addresson Ubuntu and laptops, let;s take a closer look at the idea of IP Address. IP addresses can be divided on the basis of format and accessibility. IP Addresses by Format IP addresses are available in the following two major formats – IPv4 and IP...
