Abstract
Provided is a communication device including: an address acquiring unit that acquires an IP address; a generating unit that generates, on the basis of the acquired IP address, a special reverse lookup domain name which is different from a standard reverse lookup domain name serving as a key for obtaining a domain name corresponding to the acquired IP address through a reverse DNS lookup; and a reverse-DNS-lookup processing unit that performs the reverse DNS lookup using the generated special reverse lookup domain name as a key, and acquires node descriptor data, which is different from the domain name and is associated with a communication device corresponding to the IP address acquired by the address acquiring unit.
Claims11
A communication device, comprising:
- an address acquiring unit that acquires an IP (Internet Protocol) address;
- a generating unit that generates, on the basis of the IP address acquired by the address acquiring unit, a special reverse lookup domain name which is different from a standard reverse lookup domain name serving as a key for obtaining a domain name corresponding to the IP address through a reverse DNS (Domain Name System) lookup;
- and
- a reverse-DNS-lookup processing unit that performs the reverse DNS lookup using, as a key, the special reverse lookup domain name generated by the generating unit, and acquires node descriptor data, which is different from the domain name and is associated with a communication device corresponding to the IP address acquired by the address acquiring unit.
A communication method, including:
- acquiring an IP (Internet Protocol) address;
- generating, on the basis of the acquired IP address, a special reverse lookup domain name which is different from a standard reverse lookup domain name serving as a key for obtaining a domain name corresponding to the acquired IP address through a reverse DNS (Domain Name System) lookup;
- performing the reverse DNS lookup using the generated special reverse lookup domain name as a key;
- and
- acquiring node descriptor data, which is different from the domain name and is associated with a communication device corresponding to the acquired IP address.
A non-transitory computer-readable storage medium storing a program for causing a computer to realize:
- an address acquiring unit that acquires an IP (Internet Protocol) address;
- a generating unit that generates, on the basis of the IP address acquired by the address acquiring unit, a special reverse lookup domain name which is different from a standard reverse lookup domain name serving as a key for obtaining a domain name corresponding to the IP address through a reverse DNS (Domain Name System) lookup;
- and
- a reverse-DNS-lookup processing unit that performs the reverse DNS lookup using, as a key, the special reverse lookup domain name generated by the generating unit, and acquires node descriptor data, which is different from the domain name and is associated with a communication device corresponding to the IP address acquired by the address acquiring unit.
