DNS depends on extensive caching for good performance, and every DNS zone owner must
set Time-to-Live (TTL) values to control their DNS caching. Today there is relatively little …

This paper presents a detailed analysis of traces of DNS and associated TCP traffic
collected on the Internet links of the MIT Laboratory for Computer Science and the Korea …

The Domain Name System (DNS) is thought of as having the simple-sounding task of
resolving domains into IP addresses. With its stub resolvers, different layers of recursive …

In this paper, we present an analysis of a new class of domain names: disposable domains.
We observe that popular web applications, along with other Internet services, systematically …

The DNS is one of the most crucial parts of the Internet. Since the original DNS
specifications defined UDP and TCP as the underlying transport protocols, DNS queries are …

Given that the global DNS system, especially at the higher root and top-levels, experiences
significant query loads, we seek to answer the following questions:(1) How does the choice …

Operators of high-profile DNS zones utilize multiple authority servers for performance and
robustness. We conducted a series of trace-driven measurements to understand how current …

The Internet's Domain Name System (DNS) is a frequent target of Distributed Denial-of-
Service (DDoS) attacks, but such attacks have had very different outcomes---some attacks …

In principle, a network can transfer data at nearly the speed of light. Today's Internet,
however, is much slower: our measurements show that latencies are typically more than …

The performance and operational characteristics of the DNS protocol are of deep interest to
the research and network operations community. In this paper, we present measurement …
