System and method for offering a fixed internet protocol address to a client device
View Patent ↗A method for offering a fixed Internet protocol (IP) address to a client device is provided. The method includes recording a client device ID and an IP address assigned to the client device by a dynamic host configuration protocol (DHCP) server. The method further includes sending a renewing request periodically to the DHCP server to renew the IP address in response to the determination that the client device is not powered on. Furthermore, the method includes sending an offering message comprising the client device ID and the IP address to the client device until the client device accepts the offering message in response to the determination that the client device is powered on.
1. A system for offering a fixed Internet protocol (IP) address to a client device, the system comprising:
a recording module configured for recording a client device ID and an IP address assigned to the client device by a dynamic host configuration protocol (DHCP) server;
a determining module configured for determining if the client device is powered on;
a sending module configured for periodically sending a renewing request to the DHCP server to renew the recording IP address and make the recording IP address not be withdrawn by the DHCP server in response to the determination that the client device is not powered on;
the sending module further configured for periodically sending an offering message comprising the recording client device ID and the recording IP address to the client device until the client device accepts the offering message in response to the determination that the client device is powered on, and making the client device use the recording IP address again; and
at least one hardware processor for executing the recording module, the determining module and the sending module.
2. The system of claim 1 , wherein the client device ID is a media access control (MAC) address of the client device.
3. The system of claim 1 , wherein the offering message further comprises the duration of the IP address.
4. The system of claim 1 , wherein the client device is selected from the group consisting of a personal computer (PC), a network server, a hypertext transfer protocol (HTTP) server, and a file transfer protocol (FTP) server.
5. A method, executing on hardware, for offering a fixed Internet protocol (IP) address to a client device, the method comprising:
recording a client device ID and an IP address assigned to the client device by a dynamic host configuration protocol (DHCP) server;
sending a renewing request periodically to the DHCP server to renew the recording IP address and make the recording IP address not be withdrawn by the DHCP server in response to the determination that the client device is not powered on; and
sending an offering message comprising the recording client device ID and the recording IP address to the client device until the client device accepts the offering message in response to the determination that the client device is powered on, and making the client device use the recording IP address again.
6. The method of claim 5 , wherein the client device ID is a media access control (MAC) address of the client device.
7. The method of claim 5 , wherein the offering message further comprises the duration of the IP address.
8. The method of claim 5 , wherein the client device is selected from the group consisting of a personal computer (PC), a network server, a hypertext transfer protocol (HTTP) server, and a file transfer protocol (FTP) server.
9. A non-transitory storage medium having stored thereon instructions that, when executed by a modem, causing the modem to perform a method for offering a fixed Internet protocol (IP) address to a client device, the method comprising:
recording a client device ID and an IP address assigned to the client device by a dynamic host configuration protocol (DHCP) server;
sending a renewing request periodically to the DHCP server to renew the recording IP address and make the recording IP address not be withdrawn by the DHCP server in response to the determination that the client device is not powered on; and
sending an offering message comprising the recording client device ID and the recording IP address to the client device until the client device accepts the offering message in response to the determination that the client device is powered on, and making the client device use the recording IP address again.
10. The non-transitory storage medium of claim 9 , wherein the client device ID is a media access control (MAC) address of the client device.
11. The non-transitory storage medium of claim 9 , wherein the offering message further comprises the duration of the IP address.
12. The non-transitory storage medium of claim 9 , wherein the client device is selected from the group consisting of a personal computer (PC), a network server, a hypertext transfer protocol (HTTP) server, and a file transfer protocol (FTP) server.
