Frequently asked questions

What is the difference between an IP address and a MAC address?

An IP address is given to a device by the network it joins, and it changes when the device joins a different network. A MAC address is fixed in the device's network hardware by the manufacturer and identifies that piece of hardware itself. Broadly, the IP address says where the device currently is; the MAC address says which device it is.

What is the difference between an IP address and a domain name?

A domain name such as example.com is a readable label for humans; the IP address is the number machines actually use to route data. The domain name system translates one into the other, so typing a name in a browser results in a lookup that returns an address.

Is an IP address the same as a physical location?

No. It indicates the network connection a device is using, which usually narrows things down to a city or region and to the internet provider involved. It does not identify a street address or a person by itself.

What is the meaning of IP address?

"IP address" (noun) means a number assigned to a device so that other devices on a network can find it and send data to it, in the same way a postal address tells a courier where to deliver a parcel.
