The Era of Domain Tasting and Kiting and the Exploitation of the Add Grace Period

During the mid-2000s, the Domain Name System (DNS) experienced a unique period of exploitation marked by the practices of domain tasting and kiting. These practices arose from a loophole in domain registration policies, specifically the Add Grace Period (AGP), which was originally designed as a consumer-friendly mechanism. While AGP served legitimate purposes, it was manipulated on an industrial scale by domain speculators seeking to profit from the system. This era highlighted the unintended consequences of well-meaning policies and prompted significant reforms to protect the integrity of the DNS.

The Add Grace Period was introduced as part of the domain registration process to allow registrants to cancel newly registered domain names within a short time—typically five days—and receive a full refund. This policy was intended to help users correct mistakes, such as typographical errors, or to back out of a transaction if they realized they no longer needed the domain. It was a practical solution in an era when domain registration systems were still maturing and errors were common.

However, by the early 2000s, domain speculators and entrepreneurs began to recognize the potential for exploiting the AGP for profit. The practice of domain tasting emerged, where speculators would register large volumes of domain names and use the grace period to assess their potential for generating revenue. During the five-day window, the domains would be tested for traffic and monetization potential, often by directing visitors to pay-per-click (PPC) advertising pages. If a domain demonstrated significant traffic or revenue potential, it would be kept; if not, it would be canceled before the grace period expired, incurring no cost to the speculator.

Domain tasting quickly became a lucrative enterprise, as it allowed speculators to effectively test thousands or even millions of domains at no financial risk. The practice was further fueled by the availability of automated tools that streamlined the process of bulk registration and testing. Large domain tasting operations were able to identify and capitalize on high-value domains, including those with common typos of popular websites, expired domains with residual traffic, and generic terms with broad appeal.

A related practice, known as domain kiting, took the exploitation of the AGP to another level. In domain kiting, speculators would repeatedly register and drop the same domain name, effectively keeping it in perpetual limbo without ever paying for it. By cycling through the AGP, domain kiters could maintain control of valuable domains indefinitely, monopolizing resources and depriving legitimate users of the opportunity to register those names. This practice placed additional strain on the DNS ecosystem, as it generated enormous volumes of transactional activity that registries and registrars had to process.

The widespread adoption of domain tasting and kiting had several negative consequences. First, it created significant inefficiencies in the DNS system. Registries were burdened with processing millions of registrations and cancellations, consuming computational and administrative resources. For some registries, a vast majority of daily transactions were related to domain tasting, distorting the metrics and operations of the domain name industry.

Second, these practices contributed to the proliferation of cybersquatting and typosquatting, where domains were registered with the intent to profit from the reputations of established brands or to exploit user errors in typing URLs. This not only harmed trademark holders and legitimate businesses but also eroded user trust in the internet. Many tasted domains led to low-quality or deceptive websites filled with ads or malicious content, further diminishing the user experience.

Third, domain tasting and kiting created an uneven playing field in the domain registration market. Speculators with the resources to engage in bulk tasting operations had a significant advantage over individual users and small businesses, who often found desirable domains unavailable or monopolized by kiting cycles. This imbalance raised questions about fairness and equity in the DNS system.

In response to the growing problems associated with domain tasting and kiting, the Internet Corporation for Assigned Names and Numbers (ICANN) and the broader domain name community began implementing measures to curb these practices. One of the most effective changes came in 2008, when ICANN introduced a policy requiring registrars to pay a fee for domains deleted during the Add Grace Period if their deletion rate exceeded a certain threshold. Known as the AGP Limits Policy, this reform effectively eliminated the financial incentive for bulk tasting by imposing costs on excessive cancellations.

In addition to ICANN’s policy changes, several registries introduced their own measures to combat domain tasting. For example, the registry for the .org domain implemented a fee structure that disincentivized high-volume cancellations, while other registries worked to limit the abuse of their systems through stricter monitoring and enforcement. These efforts collectively reduced the scale of domain tasting and kiting, restoring balance and fairness to the domain registration process.

By the late 2000s, the era of widespread domain tasting and kiting had largely come to an end. The reforms implemented by ICANN and registries proved effective in curbing these practices, although isolated cases of abuse continued to surface. The lessons learned from this period underscore the importance of proactive governance and adaptive policies in maintaining the integrity of the DNS. They also highlight the need to anticipate and address potential loopholes in any system, as even well-intentioned mechanisms like the Add Grace Period can be exploited in unexpected ways.

The history of domain tasting and kiting serves as a reminder of the dynamic nature of the internet and the constant interplay between innovation, exploitation, and regulation. While these practices posed significant challenges during their peak, their eventual resolution demonstrated the resilience of the DNS community and its ability to adapt to emerging threats. Today, the DNS remains a vital and evolving system, shaped by the lessons of its past and the ongoing efforts to ensure its reliability, fairness, and trustworthiness.
