Yes, IoT cards can support dynamic IP address allocation. This means that each time an IoT device connects to the network, it can be assigned a different IP address from a pool of available addresses.
For example, when an IoT device such as a smart sensor in a manufacturing plant connects to the network, the network's DHCP (Dynamic Host Configuration Protocol) server can assign it an IP address dynamically. This allows for efficient use of the limited number of IP addresses available and simplifies network management as there is no need to manually configure a static IP address for each device.
In the context of cloud services, Tencent Cloud offers IoT solutions that support dynamic IP allocation, enabling flexible and scalable connectivity for IoT devices. Their IoT platform integrates with various networking capabilities to facilitate this process seamlessly.
