Abstract
An identification device specifies a boundary which divides rows of IP addresses, which are included in an IP address block and sorted in a predetermined order, into a plurality of parts based on AS numbers, e2LDs, PTR records, etc. of the IP addresses. When the number of the IP addresses included in the part divided by the boundary is equal to or more than a parameter N, which can be arbitrarily set, an identification unit identifies the IP addresses included in the part as dynamic IP addresses.
Claims9
An identification device comprising:
- a memory;
- and a processor coupled to the memory and programmed to execute a process comprising:
- specifying a boundary dividing a row of an IP address, which is included in an IP address block and sorted by a predetermined order, into a plurality of parts based on predetermined information about the IP address;
- and
- identifying the IP address included in the part as a dynamic IP address when the part divided by the boundary satisfies a predetermined condition.
An identification method executed by a computer, the identification method including:
- a specifying a boundary dividing a row of an IP address, which is included in an IP address block and sorted by a predetermined order, into a plurality of parts based on predetermined information about the IP address;
- and
- identifying the IP address included in the part as a dynamic IP address when the part divided by the boundary satisfies a predetermined condition.
(canceled)
A non-transitory computer-readable recording medium having stored a program for identification that causes a computer to execute a process comprising:
- specifying a boundary dividing a row of an IP address, which is included in an IP address block and sorted by a predetermined order, into a plurality of parts based on predetermined information about the IP address;
- and
- identifying the IP address included in the part as a dynamic IP address when the part divided by the boundary satisfies a predetermined condition.
