Which of the following is not supported by IPv6?Question 10Select one:a.LAN multicastb.IP multicastc.IP unicastd.LAN broadcast

Step 1: Break Down the Problem

In this question, we need to identify which option is not supported by IPv6. The options provided include:

1. LAN multicast
2. IP multicast
3. IP unicast
4. LAN broadcast

Step 2: Relevant Concepts

To address the question, we need to understand what each term means in the context of IPv6:

• LAN Multicast: Refers to sending packets to multiple hosts on a local area network.
• IP Multicast: A method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission.
• IP Unicast: Sending packets from one sender to one receiver.
• LAN Broadcast: Sending packets from one sender to all devices on a local area network.

Step 3: Analysis and Detail

• IPv6 Multicast Support: IPv6 supports IP multicast and allows for efficient data transmission to multiple destinations.
• IPv6 Unicast Support: IPv6 supports IP unicast, allowing for one-to-one communication.
• IPv6 LAN Multicast Support: Generally, LAN multicast is supported under IPv6.
• IPv6 LAN Broadcast: IPv6 does not support broadcast messages. Instead, it uses multicast for similar purposes.

Step 4: Verify and Summarize

Based on the analysis, the only method listed that is not supported by IPv6 is LAN broadcast. IPv6 replaces broadcast with multicast methods, thereby avoiding broadcast traffic issues in networking.

Final Answer

d. LAN broadcast is not supported by IPv6.
