Abstract
A method of searching an IP address is provided. A user interface broadcasts an ICMP request packet to an internet protocol (IP) based network. The ICMP request packet includes a first message type undefined before, a first code number and host information to be searched at the data portion. An IP-related device, thinking the ICMP request packet destined for it, sends out an ICMP reply packet to the user interface. The ICMP reply packet includes a second message type undefined before, a second code number and the host information of the IP-related device at the data portion. The user interface thus obtains an IP address of the IP-related device in accordance with the information of the ICMP reply packet.
Claims16
A method of searching an IP address, comprising:
- broadcasting an ICMP request packet from a user interface to an internet protocol (IP) based network, said ICMP request packet including a first message type undefined before, a first code number and host information to be searched at the data portion;
- when an IP-related device corresponds to said host information, the IP-related device sends out an ICMP reply packet to the user interface, said ICMP reply packet including a second message type undefined before, a second code number and the host information of the IP-related device at the data portion, and otherwise, the IP-related device discards said ICMP reply packet;
- and
- obtaining an IP address of the IP-related device in accordance with the information of said ICMP reply packet.
