ICANN has been governing the Domain Name System(DNS) "technically" since 1998. The architecture is called Internet Governance, and it brings about many different discourses; "What does that govern?", "Who delegate its role to ICANN?"," How could the regime ensure fairness?" etc. This article will analyze on Internet Governance by applying the government approach of Foucault, and try to compare two parts, the 'core' and the 'edge' of Internet Governance for method. Whereas the 'core' of it refers the site that be governed by the formal contract directly, the 'edge' as the rest of it means informal friendly relations with ICANN. The 'core' rule was stemmed from technological community such as IAB or IETF historically. They had invented new world and its population to integrate the technical order as protocol and the semiotic order as language, that be based on new government mode. On the other hand, ".KR" domain, one of the 'edges', has been evolved into more heterogeneous system, through contest and conflict between traditional state and Internet Governance. The governed object of ".KR" domain is situated in the crossing of each other the 'protocol user', the 'language-semiotic user' and the' geographical resident'. Here the 'geographical resident' rule was weird for DNS, so that shows the internal lack of Internet Governance. It needs to move to the concept of 'Hangeul(Korean-language) user' rather than the 'geographical resident'.

Given a domain, client applications over the Internet are in support of the DNS (Domain Name System) to get its corresponding IP address. Currently, only domain names expressed by ASCII code are recognized over the Internet. This enforces the usage of ASCII domain names even in countries which use languages based on multilingual code other than ASCII code. In this paper, we present a methodology to support multilingual domain names on top of the existing DNS. The methodology is based on code translation of domain names in multilingual code into ASCII code via UTF5. We implement a gateway, called Proxy Hangul DNS (P-HDNS) based on the proposed methodology. This paper presents the principles of the methodology and the implementation details of P-HDNS.

In the current digital age, most of the countries in the world recognize the electronic business to be a very prospective area in the future and plan to activate for the preoccupation of the business. As a result, this led a rapid increase of the electronic business volume. Electronic business takes place in the cyber space, using internet. However, the intellectual property rights have a high degree of possibility of being infringed as the digitalized intellectual property is easy to receive, copy and transmit in the cyber space. The language structure on the web, represented by HTML, makes easier to copy the intellectual property. And, as the internet has no national boundary, the infringement of the intellectual property rights is easier regardless of country, which could lead to the commercial disputes between the concerned countries. There are in fact many legal disputes nowadays on the infringement of the intellectual property rights in such field as computer programming, infringement of the copyright, business model patent and infringement of the trademark right on the registered name of the domain. It is, therefore, time now to prepare a new theory or legal system to protect the intellectual property rights on copyright, patent and trademark right so as to comply with the digital environment together with such a splendid growth of "electronic business." USA and Germany are nowadays making a significant movement on the legislation of the electronic business, and this study will focus on the legislative contents, judicial precedents and interpretation of law in the above countries.

Since the Arbitration Law of China took effect in 1995, arbitration has grown with the economy. At the end of 2009, there were 202 arbitration institutions in China. Among them, China International Economic and Trade Arbitration Commission(CIETAC) has adopted online arbitration and has settled internet domain name disputes since 2001. CIETAC Domain Name Dispute Resolution Center(DNDRC) has accumulated abundant experiences of online arbitration in the field of domain name disputes. Based on those experiences, on 1 May 2009, CIETAC implemented the CIETAC Online Arbitration Rules(Rules') to regulate the resolution of e-business disputes as well as other business disputes. With this background, this article aims to study the status quo, practices and issues of online arbitration conducted by CIETAC. For the purpose of the article, a general picture of online arbitration is outlined first, followed by introducing the steps of the online arbitration procedure. According to the 'Rules', the entire arbitration process is conducted using online communication methods which are cost-effective and efficient. To facilitate the development of online arbitration, legal barriers need to be removed. This article considers main legal issues of online arbitration in China and proposes amendment to Chinese Arbitration Law, in particular, the recognition of the validity of electronic arbitration agreements and awards.

The referents of internet addresses are no longer limited to web sites. A new address service by the international organization for the internet address (ICANN) introduces an open space for the TLD (Top Level Domain) strings so that each service, content, product, and other linguistic expressions may be allowed. The open TLD addresses are more suitable for representing the address of service units, contents, or products. In this paper, as an alternative to static Internet address service to return a consistent mapping result regardless of a user-specific different requirements, we design a dynamic internet address mapping model that returns mapping result to suit user particular requirements. In addition, we propose a method for implementing a internet address service without any changes in the existing domain protocols. It may implement a dynamic internet address by attaching to a encoded user's metadata and environment data within a internet address representation, and adding the module for dynamic mapping to the name servers. Through this proposal, trying to expand the functions of internet address, it is expected to be able to provide customized informaiton retrieval services for each user by using just internet address.

현재 인터넷을 구성하고 있는 두가지 중요 이름공간(name space)인 IP(Internet Protocol) 주소와 DNS(Domain Name Service) 이름의 단점을 보완하기 위해 연구되고 있는 HIP(Host Identity Protocol)는 IP와 트랜스포트 계층 사이에 새로운 계층과 프로토콜을 제안함으로써 제한된 형태의 신뢰성을 제공하고 이동(mobility), 멀티홈(multihome), 동적 IP주소변경 등을 지원하며 DoS(Denial of Service) 공격 등을 방어한다. 본 논문에서는 현재까지 IETF에서 진행된 HIP관련 연구 동향을 분석한다.

Recursive DNS is configured as primary or secondary DNS on user PC and performs domain name resolution corresponding user's DNS query. At present, the amount of DNS traffic is occupied high rate in the total internet traffic and the internet traffic would be increased by failure of IPv6 DNS queries and responses as IPv6 transition environment. Also, existing Recursive DNS service mechanisms is unstable on malicious user's attack same as DoS/DDoS Attack and isn't provide to user trust DNS service fail-over. In this paper, we propose IPv6 Recursive DNS service mechanisms for based on anycast for improving stability. It is that fail-over Recursive DNS is configured IPv6 Anycast address for primary Recursive DNS's foil-over. this mechanisms increases reliability and resiliency to DoS/DDoS attacks and reduces query latency and helps minimize DNS traffic as inducing IPv6 address.

Domain name system (DNS) is a primary identification mechanism for Internet applications. However, DNS resolutions often take an unbearably long time, and this could seriously impair the consistency of the service quality of Internet applications based on DNS such as World Wide Web. Several approaches reduce DNS resolution time by proactively refreshing expired cached records or prefetching available records beforehand, but these approaches have an inherent problem in that they cause additional DNS traffic. In this paper, we propose a DNS resolution time reduction scheme, named renewal using piggyback (RUP), which refreshes expired cached records by piggybacking them onto solicited DNS queries instead of by issuing additional DNS queries. This method decreases both DNS resolution time and DNS traffic since it reduces the number of queries generated to handle a given DNS resolution without generating additional DNS messages. Simulation results based on two large independent DNS traces show that our proposed approach much reduces not only the DNS resolution time but also the DNS traffic.

Internet mail has become a common communication method to send and receive an amount of data due to the tremendous high speed Internet service increment. But in other respect, the risk and damage of Junk mail is growing rapidly and nowadays Junk mail delivery problem is becoming more serious, because this is used for an attack or propagation scheme of malicious code. It's a most dangerous dominant cause for computer system accident. This paper shows the Junk mail characteristic which is based on the analysis of mail log in reality and then shows the implementation of the FQDN (Fully Qualified Domain Name) check and Personalized classification system and evaluates its performance.

Distributed Denial-of-Service (DDoS) attacks towards name servers of the Domain Name System (DNS) have threaten to disrupt this critical service. This paper studies the vulnerability of the cache server to the flooding DNS query traffic. As the resolution service provided by cache server, the incoming DNS requests, even the massive attacking traffic, are maintained in the waiting queue. The sojourn of requests lasts until the corresponding responses are returned from the authoritative server or time out. The victim cache server is thus overloaded by the pounding traffic and thereafter goes down. The impact of such attacks is analyzed via the model of queuing process in both cache server and authoritative server. Some specific limits hold for this practical dual queuing process, such as the limited sojourn time in the queue of cache server and the independence of the two queuing processes. The analytical results are presented to evaluate the impact of DDoS attacks on cache server. Finally, numerical results are provided for further analysis.
