privatelocal

Privatelocal is a term used in computer networking to describe the scope of addresses and services that are confined to a private local network rather than reachable on the public Internet. It commonly indicates that the addresses are non-routable on the public Internet and are used only within a local area network (LAN). In IPv4, the private address spaces defined by RFC 1918 — 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 — are typical examples of privatelocal addressing. For IPv6, private local addressing is provided by unique local addresses in the fc00::/7 range. Privatelocal setups often rely on a router performing network address translation (NAT) or a firewall that blocks inbound traffic from the Internet, while internal devices can communicate and provide services to each other. DHCP servers and local DNS services are commonly used to manage addressing and name resolution within privatelocal networks.

Privatelocal is used in homes, offices, data centers, and virtual environments to isolate devices, save public IP space, and enable flexible internal communication. When services must be exposed externally, port forwarding, reverse proxies, or public DNS records can bridge the privatelocal network to the Internet. Security considerations include proper segmentation, strong internal access controls, and monitoring to prevent lateral movement within the private network.
