US 2003/0145073 A1 · Domain name management method and system therefor

Abstract

A method of managing domain names for dynamically or relatively statically allocated IP addresses over a network based on a transmission control protocol/Internet protocol (TCP/IP) is provided. Here, being relatively static means that an identical IP address is consecutively allocated at least twice by a dynamic host configuration protocol (DHCP) routine. In the method, a DHCP server maintains an information pair of an IP address and a hardware identification and broadcasts renewed contents to a domain name service (DNS) server if there is a renewal of the information pair. A DHCP client maintains an information pair of an IP address and a hardware identification and broadcasts renewed contents to the DNS server if there is a renewal of the information pair. The DNS server receives the information pairs of an IP address and a hardware identification from the DHCP server and the DHCP client and adds the information pair of an IP address and a hardware identification received from the DHCP server to database for storing information pairs of an IP address and a hardware identification. The DNS server adds the information pair of an IP address and a hardware identification received from the DHCP client to the database or renews the database using the IP address-hardware identification information pair received from the DHCP client. According to this method, the DHCP server and the DHCP client can transmit an information pair of an IP address and a hardware identification to the DNS server, so that a domain name service with respect to a dynamically or relatively statically allocated IP address can be provided.

Dependent claims

A method of managing domain names over a network including a dynamic host configuration protocol (DHCP) server, a DHCP client, and a domain name service (DNS) server, the method comprising:

maintaining at the DHCP server an information pair of an Internet protocol (IP) address and a hardware identification and broadcasting renewed contents from the DHCP server to the DNS server if there is a renewal of the information pair;
maintaining at the DHCP client an information pair of an IP address and a hardware identification and broadcasting renewed contents from the DHCP client to the DNS server if there is a renewal of the information pair;
and
at the DNS server, receiving the information pairs from the DHCP server and the DHCP client, adding the information pair received from the DHCP server to database for storing information pairs of an EP address and a hardware identification, and adding the information pair received from the DHCP client to the database or renewing the database using the information pair received from the DHCP client.

A system for managing domain names over a network including a dynamic host configuration protocol (DHCP) server, a DHCP client, and a domain name service (DNS) server, the system comprising:

a DHCP server apparatus including the DHCP server for dynamically allocating an Internet protocol (IP) address at the request of the DHCP client, a first translator for relatively statically allocating an IP address and storing an information pair of the relatively statically allocated IP address and a hardware identification, and a transmitter for transmitting the information pair stored in the first translator;
a DHCP client apparatus including the DHCP client, which stores an information pair of an allocated IP address and a hardware identification and uses a dynamically or relatively statically allocated IP address, and a transmitter for transmitting an information pair of a dynamically allocated IP address and a hardware identification;
and
a DNS server apparatus including the DNS server for maintaining a database for storing information pairs of an IP address and a hardware identification and responding to a DNS inquiry, a receiver for receiving information pairs of an IP address and a hardware identification from the DHCP server apparatus and the DHCP client apparatus, and a second translator for transmitting the information pairs received via the receiver to the DNS server.
