In the context of this wiki and computing in general, LAN refers to a l'''ocal area network'''. A device connected to a '''local area network''' is generally able to communicate with other devices within the '''LAN''' without having to cover larger distances or access the internet. Usually, this term refers to the network within an organization, the network of a household, or the network of another entity. The devices connected to a LAN are typically configured behind a layer of obfuscation like NAT Network Address Translation<ref>{{Cite web |title=Network Address Translation (NAT) |url=https://www.geeksforgeeks.org/computer-networks/network-address-translation-nat/ |url-status=live |access-date=2025-08-12 |website=Geeks for Geeks}}</ref> all sharing one or more public IP addresses connecting the '''LAN''' to the internet. Generally, the devices on a LAN are assigned IP addresses in the private range<ref>{{Cite web |date=2010-06-15 |title=Private-Use IP Addresses |url=https://www.iana.org/help/private-addresses |url-status=live |website=IANA Internet Assigned Numbers Authority}}</ref>.
