What's my IP address

What's my IP address
Internet Protocol Address is a unique string of numbers that identifies a computer or a server on a network.
- An IP address can be private, for use on a LAN/WLAN, or public, for use on the Internet or other a WAN.
- An IP address can be determined statically (assigned to a computer by a system administrator) or dynamically (assigned by another device on the network on demand).
- The IP address is usually expressed as four decimal numbers, each ranging from 0 to 255, separated by periods. For example, 127.0.0.1.

You can use an IP address to send a note to a specific computer. To receive notes you need to provide a sender with your computer IP address.

Detect personal public IP address provided by your ISP (for sending notes over the Internet)

Note:You may have:

personal static and public IP address at the same time if you have direct connection and your IP address in ISP's network and in outside world is the same

personal static IP address but IP address you see on your computer is different from your public IP address.

personal dynamic IP address - if you connect through the dial-up/ADSL.

non-personal static/dynamic IP address. If your ISP has the same public IP address for a range of users (e.g. for your office, building, etc.), you don't have an easy way to receive notes over the Internet. We recommend you to contact your ISP to try to resolve the problem.

If you don't know your IP address, you can:

consult your ISP

use different IP tests.

use a command-line utility ipconfig

Note: If you have a dynamic IP address, you should determine your IP address each time after you connect to the Internet
