Network address prefixed by 1110 is aa)Class A addressb)Multicast addr...
Answer:
The network address prefixed by 1110 is a multicast address.
Explanation:
When an IP address is prefixed with 1110, it indicates that it is a multicast address. Multicast addresses are used for one-to-many communication, where a single packet is sent to multiple hosts at the same time. This is different from unicast addresses, which are used for one-to-one communication, and broadcast addresses, which are used for one-to-all communication.
Here's a breakdown of the options:
- Class A address: Class A addresses have a prefix of 0, indicating that the network address starts with 0. The prefix 1110 does not match this pattern, so it is not a Class A address.
- Multicast address: Multicast addresses have a prefix of 1110, indicating that the network address starts with 1110. The given address matches this pattern, so it is a multicast address.
- Class B address: Class B addresses have a prefix of 10, indicating that the network address starts with 10. The prefix 1110 does not match this pattern, so it is not a Class B address.
- Reserved address: Reserved addresses are special addresses that are reserved for specific purposes. The given address is not specified as a reserved address, so it is not a reserved address.
Therefore, the correct answer is option B: Multicast address.

Explanation:
The network address prefixed by 1110 is a multicast address.
Classful IP Addressing:
In classful IP addressing, the IP address is divided into classes based on the value of the first few bits of the address. There are three main classes - Class A, Class B, and Class C.
- Class A addresses start with a 0 bit in the first octet and have a range from 1.0.0.0 to 126.0.0.0. The first octet is reserved for the network address, and the remaining three octets are used to identify hosts on the network.
- Class B addresses start with a 10 bit pattern in the first octet and have a range from 128.0.0.0 to 191.255.0.0. The first two octets are reserved for the network address, and the remaining two octets are used to identify hosts on the network.
- Class C addresses start with a 110 bit pattern in the first octet and have a range from 192.0.0.0 to 223.255.255.0. The first three octets are reserved for the network address, and the remaining octet is used to identify hosts on the network.
Multicast Address:
A multicast address is a special type of IP address that is used to send a single packet to multiple hosts simultaneously. These addresses are used for applications such as video streaming, online gaming, and audio conferencing. Multicast addresses are identified by the first four bits set to 1110.
The range of multicast addresses is from 224.0.0.0 to 239.255.255.255. The first octet is always 224 or greater, indicating that it is a multicast address.
Answer:
In the given question, the network address is prefixed by 1110, which means it falls into the range of multicast addresses. Therefore, the correct answer is option B) Multicast address.
