Abstract
The present invention relates to a domain name service system and method thereof. According to the present invention, a domain name service can be provided through a mobile host and domain name servers having smallest hop counts, based on position information on the domain name servers included in external links. Therefore, a domain name service can be provided within a short time regardless of operating modes of the domain name servers. Furthermore, it is possible to reduce system traffic since the addresses of optimal domain name servers are provided to edge routers.
