  • Method for domain name system spoofing in local network system
    Publication number: 20030200335
    Abstract: A method and system can access local network access devices whose IP (Internet Protocol) addresses are not registered to a DNS (Domain Name System) server using domain names. For this, a local network gateway registers the IP addresses and the domain names mapped to the IP addresses thereto. If a domain name contained in a received DNS query packet is registered to the local network gateway, the local network gateway changes a DNS query packet into a DNS answer packet containing an IP address corresponding to the registered domain name and then transmits the DNS answer packet to a local personal computer. Otherwise, the local network gateway passes the DNS query packet to an external network as it is.
