Abstract

A method for naming a DNS for an IoT device comprises the steps of: receiving a first message including a DNS search list by a device connected to a network on the basis of IPv6 protocol; generating, by the device, a domain name including model information and an identifier of the device; performing, by the device, a redundancy check for the domain name on the basis of a neighbor discovery (ND) protocol; and, when the domain name is not redundant, registering the domain name and IPv6 address for the device into a DNS server on the basis of a node information (NI) protocol by a domain name-collecting apparatus connected to the network.

Claims

1. A method for naming DNS for an IoT device, the method comprising:

receiving, by a device connected to a network according to an IPv6 protocol, the first message including a DNS search list;

generating, by the device, a domain name including model information and an identifier of the device;

performing, by the device, a duplicate check on the domain name according to a Neighbor Discovery (ND) protocol; and

registering, by a domain name collecting device connected to the network, the domain name and an IPv6 address for the device in a DNS server according to a Node Information (NI) protocol when the domain name is not duplicated.

2. The method of claim 1, wherein the device receives the first message through a Router Advertisement (RA) option or a Dynamic Host Configuration Protocol (DHCP) option according to an IPv6 standard in the receiving step.

3. The method of claim 2, wherein the domain name collecting device or a router connected to the network transmits the first message to the device according to the RA option or the DHCP option.

4. The method of claim 1, wherein the domain name includes at least one of an object_identifier, a model name, a model category indicating a type of the device, a different device identifier for each device having the same model name, and a network domain of the device.

5. The method of claim 1, wherein the model information includes at least one of a model name of the device, a producer or a seller of the device, and a model category indicating a type of the device.

6. The method of claim 1,

wherein the DNS search list includes a DNS domain suffix, and

wherein the domain name includes at least one of an object_identifier, a model name, a model category indicating a type of the device, a different device identifier for each device having the same model name, and a DNS domain suffix.

7. The method of claim 1, wherein when the domain name is duplicated the method further comprises,

generating, by the device, a new domain name including a new identifier that is changed from the identifier;

and

performing a duplicate check on the new domain name.

8. The method of claim 1, wherein the device generates the domain name further including location information for the device in the generating step.

9. The method of claim 8, wherein the location information is geographical coordinate information of a location where the device is located.

10. The method of claim 8, wherein the location information is relative location information with respect to another device located around the device.

11. The method of claim 8, wherein the location information is relative location information measured using a sensor device measuring a location moving at a reference point.

12. The method of claim 11, wherein the device receives the relative location information measured from the sensor device.

13. The method of claim 8, wherein the location information is inputted into the device through a user terminal connected to the network.

14. The method of claim 1, wherein the step of registering comprises:

transmitting, by the domain name collecting device, a Node Information (NI) query to the device;

transmitting, by the device, the domain name to the domain name collecting device; and

transmitting, by the domain name collecting device, the received domain name to the DNS server.

15. The method of claim 1, further comprising, by a client device connected to the network, obtaining a domain name for the device from the DNS server and monitoring or controlling the device using the domain name.

19. The method of claim 1, wherein the device generates a domain name having a new domain suffix when moving to an area having a new domain suffix.

16. A method for naming DNS for an IoT device, the method comprising:

transmitting, by a router connected to a network according to an IPv6 protocol, a DNS search list to an IoT device through a Router Advertisement (RA) option or a Dynamic Host Configuration Protocol (DHCP) option;

generating, by the IoT device, a domain name including model information of the IoT device, an identifier, and a domain suffix included in the DNS search list; and

registering, by a domain name collecting device managing the IoT device, the domain name and an IPv6 address for the device into a DNS server according to a Node Information (NI) protocol.

17. The method of claim 16, wherein the model information includes at least one of a model name of the device, a producer or seller of the device, and a model category indicating a type of the device.

18. The method of claim 16, wherein the device generates a domain name further including location information for the device in the generating step.

20. The method of claim 16, wherein the IoT device generates a domain name having a new domain suffix when moving to an area having a new domain suffix.
