Port forwarding or port mapping allows remote computers to connect to a specific computer or service on a private network. This allows you to run a web server, game server or a service of your choosing from behind a router. When you forward a specific port on your router, you are telling your router where to direct traffic for that port.
This utility can verify the success of that process. Please refer to your routers manual or manufacturer for assistance in setting up port forwarding. Most residential ISP's block ports to combat viruses and spam.
What is my IP?
The most commonly blocked ports are port 80 and port Port 80 is the default port for http traffic. This is because the providers usually have a limited number of addresses and distribute them as needed, as never all users will be online at the same time. In your own home you get from these allocations of providers once very little. Mostly in the home network dynamic IP addresses are used, which are assigned internally by the router, but are not visible to the outside. Because without an IP address you would be completely lost as an Internet user.
IP stands for Internet Protocol and is a so-called network standard that specifies the form in which information is exchanged on the Internet. The IP is similar to a postal address or telephone number in analogue life. Every device within a data network — both on the Internet and in a small home network — needs an IP address. Each IP can only be assigned once and is not local.
It ensures that data sent in the network also arrive where they should go.

The IP consists of a whole string of numbers. Currently valid standards are IPv4 and IPv6.
For IPv4, an address consists of four numbers, each in the range , separated by periods. This looks like this: For IPv6, the newer standard, the IP consists of eight blocks of characters, which can include letters as well as numbers.
Finding the Owner of an IP Address
Whether four or eight character blocks: The number chains are difficult to remember. Especially since you not only have to remember your own address, but also your favorite websites, shops, etc. That means: For example, to call embedgooglemap. The IP address is given by your Internet provider. In contrast to the telephone number it can change — it is assigned dynamically from the address block of the respective provider. Only a few years ago, each time the computer was switched off and on again, a new IP was assigned.
Thanks to the flatrates and the continuous use of the network, it is now often days and weeks at an IP address.
Anyone wishing to deliberately change their IP address should therefore switch off the DSL router for a short time or interrupt the Internet connection on mobile devices. Incidentally, every single device in your home network has its own IP address. The gets assigned internally by the router, which is the private network and the provider is interposed.
That is, the router pulls its external IP address from the provider and then assigns internal IP address to the connected devices. In the future, however, that could change: With IPv6 comes to us such a large number of possible addresses that theoretically each user could be assigned a fixed IP identity. IPv6 is, so to speak, the future of the Internet Protocol, which has already begun.

With IPv4 currently about 4 billion addresses are available. Given the number of worldwide users and the even higher number of devices is clear: This amount of addresses is not enough anymore. With IPv6, the address space increases many times in dimensions that are difficult to survey and ensures that even in many years there will still be enough addresses available for all users and devices. For privacy reasons, it makes sense that IP addresses change.
