Quick Answer: Can A Switch Have Multiple IP Addresses?

How do I get multiple IP addresses?

The easiest way to get multiple IP addresses is to purchase them from your ISP, in a block.

Alternately, you can use an internet service provider that frequently changes IP addresses, like a PPPoE based ISP..

Why do I have 2 different IP addresses?

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. … The cable, WiFi, and two more from some “virtual” network interfaces that provides a VPN connection.

Why is a switch configured with an IP address?

If you want to be able to manage your switch remotely over the network, your switch needs an IP address. If your switch has multiple VLANs configured, and you want to be able to manage the switch from each VLAN, the switch requires an IP address on a VLAN interface in each VLAN.

How many IP addresses does a switch have?

It is a ethernet switch and it switches ethernet packets and on the level of ethernet packets there are no IP addresses. If you plug in a switch to the modem and the voip adapter and the router to the switch then you have two devices directly connecting to the modem and the internet.

Can a device have multiple IP addresses?

Yes a computer may have two or more IP address. Actually computer doesn’t have any IP address, a NIC (Network Interface Card) have IP and a computer system have more than one NIC cards hence your system may have more than two IP address each for NIC.

Can we assign IP address to layer 2 switch?

When configuring an IP address on a Layer 2 switch that has multiple VLANs, make sure the configuration includes a designated management VLAN that identifies the VLAN to which the global IP address belongs.

Does Layer 3 switch have IP address?

Switches do not care about IP addresses, nor do they even examine IP addresses as the frames flow through the switch. Instead, they forward frames based on the media access control (MAC) address. Every Ethernet device and port has its own unique 16-digit hexadecimal address.

What happens if 2 devices have the same MAC address?

In order for a network device to be able to communicate, the MAC Address it is using must be unique. … If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly. On an Ethernet LAN, this will cause a high number of collisions.

What are three characteristics of an SVI?

What are three characteristics of an SVI? (Choose three.)It is designed as a security protocol to protect switch ports.It is not associated with any physical interface on a switch.It is a special interface that allows connectivity by different types of media.It is required to allow connectivity by any device at any location.More items…•

Do switches assign IP addresses?

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). You need to assign a static IP address to your computers.

Can a switch have multiple subnets?

Switches can carry as many subnets as you want them to because they don’t know, or care, about IP routing. It’s actually fairly common in small setups to have a router (“gateway”) with multiple IP addresses, one per subnet, on a single Ethernet port.

What is the difference between a Layer 2 switch and a layer 3 switch?

A Layer 2 switch only works with MAC addresses and doesn’t interact with any higher layer addresses, such as an IP. A Layer 3 switch, on the other hand, can also do static routing and dynamic routing, which includes IP and virtual local area network (VLAN) communications.
