Abstract
Implementations for probabilistic wildcard-based DNS resolution are described. A request to validate a first subdomain is received from a domain name system (DNS) service attempting to resolve a DNS request that identifies the first subdomain. A validation outcome that indicates a guess regarding validity of the first subdomain may be determined based on a probabilistic data structure representing a set of valid subdomains. The validation outcome may be sent to the DNS service to cause the DNS service to resolve the first subdomain based on the validation outcome. In the case of the validation outcome indicating a guess of the first subdomain being valid, the first subdomain is caused to be resolved to a first common subdomain. In the case of the validation outcome indicating a guess of the first subdomain being invalid, the first subdomain is caused to be resolved to a second common subdomain.
