reititettävät

Reititettävät is a Finnish term that translates to "routable" or "can be routed." It is commonly used in the context of network engineering and telecommunications to describe a network interface, IP address, or network segment that can participate in IP routing. This means that data packets can be forwarded to and from this entity based on its IP address and the routing tables of connected devices.

In essence, a reititettävä interface or address is one that is configured to receive and send IP traffic and is recognized by routing protocols. This is in contrast to non-routable interfaces or addresses, such as those used for local loopback or private networks that are not intended to be exposed to the public internet. For example, a local area network (LAN) might use private IP address ranges that are not reititettävät on the wider internet, requiring Network Address Translation (NAT) to communicate externally.

When a network device has a reititettävä interface, it can act as a router or a host that can communicate with other devices on different networks. This capability is fundamental to the functioning of the internet and most modern computer networks, enabling the seamless transfer of data across diverse geographical locations and network infrastructures. Understanding what makes an interface or address reititettävä is crucial for network design, troubleshooting, and security.
