Front Running as it relates to the domain industry is the practice of using insider information to register a domain name that someone else wants to register in order to charge a higher price for the domain name or to get the registrant to sign the name with a particular registrar.
The public perception of domain name front running is that it is an unfair practice that harms the registrant. It is often seen as a conflict of interest for registrars and compared to insider trading.  It is worth noting that there is debate over the existence of domain name front running.
The outcome of this practice is a lack of trust between registrants and registrars and possibly extortion if the accusations of front running are verified.
- In theory, domain name front running occurs when people interested in registering domain names use WHOIS or a popular registrar's website to see if their desired domain name is taken.  The registrar or another third party then uses this search data to register the name, making it unavailable except under the registrar or third party's terms and conditions.
- In 2008, Network Solutions was accused of front running because a protective service it used put domain names searched on their site on hold for 4 days after the initial search.  The result was that if a person wanted to register the searched for domain name, they would have to register with Network Solutions or wait for the name to become available again. Network Solutions settled in a 1 million dollar class action lawsuit over the service.
- A study by ICANN's Security and Stability Action Committee (SSAC) found no proof of domain front running after completing more than 600 tests  and dismissed 120 complaints of possible front running.
- In addition, a clause in Specification 9 of the 2013 RA states that front running activities are prohibited.
- Domain name front running is not specifically addressed by U.S. law at this time.
- Another practice that may give registrars an advantage over registrants is Warehousing.
