Can a network device have more than one NIC?

By default, each network interface card (NIC) has its own unique IP address. However, you can assign multiple IP addresses to a single NIC.

Can one physical machine have several names and/or IP addresses associated with it?

Yes, one device can have multiple IP addresses. You likely already have at least one device doing that aready – your home router. The usual reason for a device to have more than one IP address is that it is present on more than one seperate subnet, or network.

Is it possible for a computer to have more than one IP address at the same time?

Yes. A computer can have more than one ip address at a time. You can specify those ip addresses by two ways as suggested by dinesh. You can specify the additional ip address in advanced properties of your network connection.

How can I use two network adapters on one machine?

Open the Network Connections window. Select the network connections to bridge. To select more than one connection at a time, press and hold the Ctrl key as you click each one. Right-click the selected icons and choose the Bridge Connections command.

Why do servers have multiple NICs?

Separation of traffic (i.e. you could have a combo web/database server, same network, put all web traffic on one NIC, db traffic on the other, makes it easier to calculate loads for traffic types). This also makes it easier to split the two later on, nobody has to change connection strings.

Can two NICs have same IP?

You won’t “give both ports the same IP address” since there will only be one “port” visible to give an IP address to. Each “LAN port”, or NIC, must have a unique IP address. It would be unusual for each of the IPs to be on the same network. The same DNS server could serve both IPs, and usually does.

Can a single interface have multiple IP addresses?

The concept of creating or configuring multiple IP addresses on a single network interface is called IP aliasing. IP aliasing is very useful for setting up multiple virtual sites on Apache using one single network interface with different IP addresses on a single subnet network.

Do switches have NIC card?

How does a network switch work? Once a device is connected to a switch, the switch notes its media access control (MAC) address, a code that’s baked into the device’s network-interface card (NIC) that attaches to an ethernet cable that attaches to the switch.
