“…Measuring the quality attributes of the DNS and investigating its potential weaknesses is a question of crucial interest [19]. Best practices [11,22] for ensuring availability and security of the DNS infrastructure recommend: (1) defining a number of name servers for each domain, (2) configuring these name servers under at least two different parent domains and (3) placing the physical name servers, hosting the zone files for the domain, in separate networks.…”

“…Quality attributes have different definitions based on the point of view of the DNS user. For example, resiliency is viewed by users as availability and viewed by providers as a combination of detection, response, resistance and recovery processes that increase overall confidence in relying on and investing in the Internet over the longterm [19].…”

“…DNS name dependencies are analysed in [4], [7] and [16], in which the potential for a large number and variety of servers affecting name resolution is demonstrated. Individual operators and independent researchers have measured various aspects of the DNS and from various prospective such as from the user, resolver or network points of view [18,19]. In [16] Deccio et al present a model of DNS name resolution from which the availability of a domain name can be quantified in the context of its deployment.…”

“…Shulman et al [2] studied the operational characteristics of the DNS infrastructure and how some factors impact resilience, stability and security of the DNS services. Casalicchio et al [19] proposed a framework for the evaluation of the health and security levels of operational DNS. To the extent of our knowledge, only very few preliminary studies for defining suitable metrics to measure the quality attributes of the DNS system have been conducted [1,7,16,19].…”

The Domain Name System (DNS) has a direct impact on the performance and dependability of nearly all aspects of interactions on the Internet. DNS relies on a delegation-based architecture, where resolution of a name to its IP address requires resolving the names of the servers responsible for that name. The graphs of the inter-dependencies that exist between name servers associated with each zone are called Dependency Graphs. We constructed a DNS Dependency Model as a unified representation of these Dependency Graphs. We utilize a set of Structural Metrics defined over this model as indicators of external quality attributes of the domain name system. We explore the inter-metric and inter-quality relations further in order to quantify the indicative power of each metric. We apply some machine learning algorithms in order to construct Prediction Models of the perceived quality attributes of the operational system out of the structural metrics of the model. Assessing these quality attributes at an early stage of the design/deployment enables us to avoid the implications of defective and low-quality designs and deployment choices and identify configuration changes that might improve the availability, security, stability and resiliency postures of the DNS.
