Evaluating the Impact of Name Resolution Dependence on the DNS

Figure 4

Resolving graph of a domain name, where the edge label “parent” indicates it is dependent on the parent domains, the label “NS” indicates it is dependent on the name servers. The resolution of this domain name involves 6 different domains and their name servers, which is symbolized by different colors in the graph. In addition, alias dependence does not appear in this figure. If a domain name has a “cname,” alias should be marked on the edge between the domain name and the cname.
