Why do we need secondary IP address?

Using secondary IP addresses on the routers or access servers allows you to have two logical subnets using one physical subnet. Many older networks were built using Level 2 bridges. The judicious use of secondary addresses can aid in the transition to a subnetted, router-based network.

What is the purpose of different IP address?

You have a different IP address for internal purposes, such as identifying your devices within a home network or inside a business office. The local or internal IP address is assigned to your computer by the router, which is the hardware that connects a local network to the internet.

What does multiple IP address mean?

IP aliasing is associating more than one IP address to a network interface. With this, one node on a network can have multiple connections to a network, each serving a different purpose. IP aliasing can be used to provide multiple network addresses on a single physical interface.

Should I have two IP addresses?

Of course it can. Although it is not at all recommended to assign multiple IP addresses on a computer until there are multiple network interface cards or NICs installed in it, you can still do so. The reason why it is not recommended to have multiple IP addresses on a single network adapter is to avoid the bottlenecks.

Can a domain name point to multiple IP addresses?

Yes, that is possible, and will need to be two A records. This is called Round-Robin DNS. Clients will semi-randomly use one of the two addresses. The certificate is not tied to the IP address, only to the domain name,so if it is installed on both servers, there should be no issues with SSL.

Should I enable secondary IP address?

Secondary addresses can help you avoid a network outage if you want to migrate your trusted network from one subnet to another. For example, if you currently use 192.168. 1.1/24 as the primary interface IP address, and you change the interface IP address to 10.0.

Can a switch have two IP addresses?

When computers are on the same IP segment, it means that the computers belong to the same network. But since the switch does not have the capability to assign IP addresses, the computers connected to it will not be able to communicate with each other. They will get an Automatic Private IP Address (APIPA).

Why is there 2 IP addresses on my wifi?

It’s because your Ethernet (cable) network card and your WiFi network card is just that, two different network interfaces. That means that to function, each of them have to have an IP address, given by your router. It’s normal behaviour.
