The term "local network" here refers to the set of computers and devices that can be reached directly from your computer without going through the Internet. For example, your home router, your network printer, or the intranet of your company are most likely on your local network, also called LAN for Local Area Network. In technical terms, this refers to the set of IP addresses defined in [RFC1918](https://tools.ietf.org/html/rfc1918).
But an application that can connect to both resources on the Internet (going through Tor) and resources on the local network (without going through Tor) can break your anonymity. For example, if a website that you visit anonymously using <span class="application">Tor Browser</span> could also connect to other web pages that are specific to your local network, then this information could reveal where you are. This is why <span class="application">Tor Browser</span> is prevented from accessing the local network in Tails.
It is impossible to access web pages on the local network using <span class="application">Tor Browser</span>. This prevents websites on the Internet from deducing your location from the content of other web pages that might be specific to your local network.
To download files from web pages on the local network, you can use the `curl` command instead. For example, to download a document available on the local network at <span class="filename">http://192.168.1.40/document.pdf</span> execute the following command:
