In this paper, we focus on the design and building of iDNS-MS by using knowledge-based system and ontological engineering technologies. iDNS-MS, developed by using web interface and expert system technology, is a unifying environment for providing plausible answers to help solve the complex DNS management problems or alleviate these DNS administration loadings. In iDNS-MS, we propose an ontolog...

This paper provides the first systematic study of DNS data taken from one of the 13 servers for the .com/.net registry. DNS’ generic Top Level Domains (gTLDs) such .com and .net serve resolvers from throughout the Internet and respond to billions of DNS queries every day. This study uses gTLD data to characterize the DNS resolver population and profile DNS query types. The results show a small ...

The Domain Name System (DNS) is a critical infrastructure of any network, and, not surprisingly a common target of cybercrime. There are numerous works that analyse higher level DNS traffic to detect anomalies in the DNS or any other network service. By contrast, few efforts have been made to study and protect the recursive DNS level. In this paper, we introduce a novel abstraction of the recur...

Distributed energy resources (DERs) including distributed generators (DGs) and controllable loads (CLs) are managed in the form of several microgrids (MGs) in active distributions networks (ADNs) to meet the demand locally. On the other hand, some loads of distribution networks (DNs) can be supplied by retailers which participate in wholesale energy markets. Therefore, there are several decisio...

The Domain Name System (DNS) is a ubiquitous part of everyday computing, translating human-friendly machine names to numeric IP addresses. Most DNS research has focused on server-side infrastructure, with the assumption that the aggressive caching and redundancy on the client side are sufficient. However, through systematic monitoring, we find that client-side DNS failures are widespread and fr...

Dieses Ergebnis und die vorher beschriebenen vergleichenden Untersuchungen weisen darauf hin, daß für die hydratationsabhängigen Konformationsänderungen der DNS in situ die Artspezifität der DNS und der Proteinkomponente im Komplex, die möglichen Artspezifitäten von Konformationseigenschaften des Komplexes und der Wechselwirkungen zwischen DNS und Protein von Bedeutung sein können. Da die Kennt...

DNS amplification attacks massively exploit open recursive DNS servers mainly for performing bandwidth consumption DDoS attacks. The amplification effect lies in the fact that DNS response messages may be substantially larger than DNS query messages. In this paper, we present and evaluate a novel and practical method that is able to distinguish between authentic and bogus DNS replies. The propo...

Hypermethylation of cell cycle regulators and increased DNA methyltransferase 1 (Dnmt1) mRNA level have been reported in hepatocarcinogenesis. However, the expression of Dnmts has not yet been examined in hepatocellular carcinomas (HCCs). We examined 13 cases of HCCs in dysplastic nodules (DNs) and 28 cases of advanced HCCs for Dnmt1 and Dnmt3a, and compared the results with those of 9 cases of...

Dysplastic nodules are premalignant neoplastic nodules found in explanted livers with cirrhosis. Genetic signatures of premalignant dysplastic nodules (DNs) with concurrent hepatocellular carcinoma (HCC) may provide an insight in the molecular evolution of hepatocellular carcinogenesis. We analyzed four patients with multifocal nodular lesions and cirrhotic background by whole-exome sequencing ...

The Domain Name System (DNS) has grown to play various of broader roles in the Internet, beyond nameto-address mapping. It provides query engine for antispam [2] and replica selection for content delivery networks (CDNs) [3]. DANE [1] provides additional source of trust by leveraging the integrity verification of DNSSEC. The wide use and critical role of DNS prompt its continuous evolution. How...
