Abstract
The technology disclosed herein enables detection of domain hijacking when a DNS resolver is performing a DNS lookup. In a particular embodiment, a method provides, in response to a request to resolve a network address corresponding to a domain name, determining that a nameserver for the domain name is suspect based on satisfaction of nameserver criteria associated with the domain name. The method further includes preventing the nameserver from being used to resolve the request in response to determining that the nameserver is suspect.
