Yes, private IP addresses are traceable, but only by other devices on your local network. Each device connected to your local network has a private IP address, and each device’s private IP address can be seen only by other devices within that network. But unlike the public IP address that...
在所有节点都正常运行时,每个节点的VIP会被分配到public NIC上;在linux下ifconfig查看,public网卡上是2个IP地址;如果一个节点宕机,这个节点的VIP会被转移到还在运行的节点上。也就是幸存的节点的public NIC这个网卡上,会有3个IP地址。 VIP 的作用: VIP并不能把用户请求转到实例上;但是可以让用户可以连通IP,不能...
Explain public and private IP addressingCompleted 100 XP 2 minutes Devices and hosts that connect directly to the Internet require a public IPv4 address. However, hosts and devices that do not connect directly to the Internet do not require a public IPv4 address....
与Public IP一样,Private IP称为私网IP或心跳IP,它也是网卡上的真实IP,每个节点在安装Oracle集群软件之前都需要事先配置Private IP。Private IP用于集群间多节点心跳同步和Cache Fusion等任务,在Oracle 12c中还需要担任Flex ASM的任务。当然,如果不设置Private IP而是由Public IP也可以去完成这些任务。但是,这样做只...

1. private IP address is used only for internal clustering processing (Cache Fusion) 私有IP用于心跳同步,这个对于用户层面,可以直接忽略,简单理解,这个Ip用来保证两台服务器同步数据用的私网IP。 2. VIP is used by database applications to enable fail over when one cluster node fails ...

whereas public IP addresses can. For instance, most home networks have a router. This router will have a public IP address that is accessible through the Internet. Devices that are behind the router such as your laptop, gaming consoles and smartphones have private IP addresses that are unique...
Private IPv4 addresses The pool of IPv4 addresses is becoming smaller, so IANA is reluctant to allocate superfluous IPv4 addresses. Technologies such as network address translation (NAT) enable administrators to use a relatively small number of public IPv4 addresses, and at the same time, ...
