Abstract: Examples disclosed herein relate to determining whether to allow access to an IP address based on a security level and domain name access information. In one implementation, a processor intercepts a response to a Domain Name System request related to a domain name and updates a security level based on the request and/or response. The processor may determine whether to forward or block the response based on the security level and a comparison of the domain name to stored information related to previous domain name access.
