The Answers are:
(a) The class of the network is B.
(b) The network ID of this network is 16 bits long as it is class B.
(c)
- A network ID, also known as a NetID, is a portion of an IP address that classifies the network for a certain host, i.e., it tells us which network the host belongs to. It is typically composed of one to four octets in dotted-decimal notation.
- Host Id is an IP address fragment that uniquely classifies a host on a given TCP/IP network. A host ID can be obtained by ANDing the IP address in binary form with the default subnet mask (in binary form). The network ID, which identifies the network to which the host belongs, is the other fragment of an IP address.
(d) The process of splitting a Class A, B, or C network into subnets is known as subnetting.
The default subnet masks for Class A are 255.0.0.0, 255.255.0.0 for Class B, and 255.255.255.0 for Class C.
(e) Here, 30 network hosts can be addressed in this network.
