c. Unique Local Addressing
d. All of these​

Answer 1

Answer:

d. unique local addressing are reqiured by lot lan

Answer 2

In a network within an IoT proxy(with provisions for tunneling), unique Local Addressing (option c) is required by IoT LAN

• The above graphics illustrate a few IoT network topologies that are limited to local areas and are comparable to standard LANs, WANs, and proxy.
• The nodes denoted by green circles have locally unique L: local link addresses or LU: local link addresses.
• Nodes under the control of a gateway have addresses that are only functional within the gateway's domain.
• The domain of another gateway may include duplicate addresses. The gateway can be located worldwide because to its distinctive (unique) network prefix.
• This method significantly reduces wasteful address waste.
• However, the nodes must use the gateway to connect to the internet.
• Utilizing local addresses that are unique within the domain of the gateway is one method of address conservation in the Internet of Things (IoT). The circles on this slide stand in for these.
• The internet-connected network has routers, each with their own set of addresses and address ranges.
• These routers are connected to a number of gateways, and only these gateways are capable of forwarding packets from the nodes to the Internet.
• These routers assign prefixes to the gates that are beneath them so that the gateways can be recognized with them.
