Question: Can A Switch Have Multiple IP Addresses?

What happens if two devices have same IP address?

For a system to communicate via a network, it must have a unique IP address.

Conflicts arise when two devices are on the same network trying to use the same IP address.

When this occurs, both computers end up not being able to connect to network resources or perform other network operations..

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.

Can multiple subnets be on same VLAN?

There’s really no reason not to put multiple subnets on the same VLAN, but there’s also probably no reason to do it. … Allows the subnets to talk directly without a router or firewall.

Can a device have multiple IP addresses?

Yes. All IP Routers (networking) are computers (hosts) with more than one IP Address. Even non-routers can have more than one IP address. Doesn’t even require additional physical NICs in the presence of virtual local area networks (VLAN).

Can there be two same IP address?

So, yes, someone else can have your same IP address. … Outside of ISP’s, and any other physical network, the IP address has to be unique. The Internet routers work with each other to develop a single route that delivers IP traffic to an address. They can’t do that if there are two people using the same address.

Can we assign IP address to layer 2 switch?

Contrary to Router/Firewall configuration, Layer 2 Switch has ports configured as Layer 2 which can’t be given an IP address, instead SVI (Switched Virtual Interface) needs to be assigned an IP address. Layer 2 Switch is assigned IP address to manage it via Telnet or SSH services.

What are three characteristics of an SVI choose three?

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…•

How many IP addresses can a device have?

In the long term, every device will hopefully have its own IP address. In the short term, you may not even have a single public IP address of your own. IPv6 Addresses for Each Device: IPv4 has less than 4.2 billion addresses, but IPv6 can offer 2128 possible IP addresses.

Can two subnets talk to each other?

Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between different networks. Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3.

Can VLANs be on different subnets?

No, VLANs don’t require different subnets. Different subnets require different subnet addresses if they ever need to be able to route and/or talk to each other) and by extension if one VLAN wants to talk to a different VLAN it must use different addresses so we can make a routing decision to the right place.

Can a switch 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. Click here for instructions.

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.
