Question
Subnetting is implemented in routing tables in the following way:Question 8Select one: A field in the IP datagram header informs the router about which address bits are used for the NetID and which for the SubnetID.The first time a router directs an IP datagram to its host, a response is sent back to inform it about the subnetting.No special mechanism is required; routers simply apply the netmasks they are given and the length of that mask may incorporate the subnet When building the routing table, the router learns from other routers which addresses have subnets.
Solution
The correct answer is: No special mechanism is required; routers simply apply the netmasks they are given and the length of that mask may incorporate the subnet.
This is because subnetting is a method for dividing a network into two or more smaller networks. It is done by applying a netmask to an IP address. The netmask is a binary pattern that is matched up with the IP address to turn part of the host ID address space into a network ID address space. This is done at the router level, and the router does not need to be informed about which bits are used for the NetID and which for the SubnetID. It simply applies the netmask it is given.
