Reititettävään

Reititettävään is a Finnish term that translates to "routable" or "assignable" in English, depending on the context. In the realm of network engineering and information technology, it most commonly refers to IP addresses or network segments that can be forwarded by routers across different networks. This contrasts with private IP addresses, which are typically used within a local network and are not routable on the public internet.

When an IP address is considered "reititettävään," it means it is part of a public address space allocated by the Internet Assigned Numbers Authority (IANA) and its regional internet registries. These addresses can be advertised and routed across the global internet infrastructure. Organizations that are assigned these public IP addresses are responsible for managing them and ensuring they are used efficiently and securely.

The concept of routable addresses is fundamental to the functioning of the internet. Without them, data packets would be unable to traverse the complex network of interconnected routers that form the backbone of global communication. Conversely, non-routable (private) IP addresses, such as those in the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 ranges, are reserved for internal use and are managed by network administrators within organizations. These private addresses are translated to public, routable addresses using Network Address Translation (NAT) when devices on a private network need to access the internet.
