The IP address displayed at the bottom of each page on the Scratch website.

An IP address (Internet Protocol address) is a unique address which determines your computer's identity on your local network (LAN), or your broadband's identity on the internet. All devices connected directly to the internet are assigned a public IP address. Devices connected to a network are assigned a local IP address. IP addresses range from to

A public IP address identifies a network connected to the World Wide Web, while a local IP address identifies a device on a local network, in the form of 192.168.x.x (or, only on your computer, or "localhost").

On the old Scratch 1.4 website, your IP address could be found at the bottom of all pages on the website.

When the Scratch Team IP-bans someone, they prevent computers with that IP address to access the site.

You can find your IP address by searching on Google, "my IP". Then it will show up in a box by where the links to other sites are.

LAN Address

An LAN network is a local-area network formed from multiple computers being connected to a router. Whenever multiple computers are on a network together, they form a LAN network, allowing them to communicate data with each other. On an LAN network, each computer has a local IP address specifically identifying itself on that network. The local IP address is subject to change but is needed for the router to know where to send its data. Without local IP addresses, a router would not know what computer the data is intended for.

Note Note: A computer not connected to a network does not have a local IP address but has a MAC address for identification.

WAN Address

Servers, routers, and other high-end data-communication machinery have their own WAN address (wide-area network). The WAN address identifies a router or server across the Internet and entire globe. For example, when accessing the Scratch website, your computer sends data to a router likely by communicating with the router's local IP address. Then, the modem, which is typically connected to the router if not part of it, finds the Scratch servers and requests certain data from it, such as the home page. Along with the requested data, the WAN address is sent so the server knows where in the world to send the information back. The information comes back to the modem/router, and then the LAN address is used to send it to the proper computer on the local network.


Ports are different connection "slots" on a target machine. For example, connecting to a website usually uses HTTP, which runs on port 80. HTTPS runs on port 443 and the cloud server uses port 531. IP addresses with ports look like this:

Note Note: This only works in Windows.
Hold the Windows key, and press "R" and type "cmd" in the box. Press enter. A black console window should open up. Type:
You should see:
