Infoblox DNS Firewall is malware protection and Domain Name Service (DNS) that blocks access to known bad domains. This service aims to reduce the number of malware infections caused by drive-by downloads, malicious downloads, and phishing, and will reduce the effectiveness of botnet infections on University computers.
Domain Name Service (DNS) translates an Internet domain name into a numerical IP address. DNS servers receive a domain query from a client and returns an IP address, connecting the client to the site they requested. Infoblox maintains a list of known harmful sites and denies connection to clients that request a site on their blacklist.
You should not see any changes. If you try to visit a domain that is on Infoblox's blacklist, you will see a block page indicating that the domain hosts known malicious content and has been blocked.
Occasionally, Infoblox will block a legitimate domain. If you believe the domain you attempted to access is legitimate, please contact the IT Help Center. They will investigate the issue and, if necessary, suggest that Infoblox remove the site from its blacklist.
