The routing table shows the IP addresses or address routes for the computers connected to the router to reach different destinations, such as the local network, the router, or the outside world beyond the router (i.e., the Internet).
Destination: The destination for the connection.
Gateway: The IP address of the router at the next hop to which frames are forwarded.
Subnet Mask : The Mask associated with the destination. This is a template that identifies the address bits in the destination address used for routing to specific subnets. Each bit that corresponds to a "1" is part of the subnet mask number; each bit that corresponds to "0" is part of the host number.
Flag: Indicates the route status.
U: Up.
!: Rejected.
G: Gateway.
H: Host.
R: Reinstate.
D: Dynamic (redirected).
M: Modified (redirected).
Metric: The number of hops or routers to the destination.
Service: The service used for the connection.
Interface: The local interface through which the next hop of this route is reached.
