BlackHole DNS

Beginning Oct. 22, 2013, a MOREnet connection is required to use BlackHole DNS.

The BlackHole DNS (BHDNS) service adds a layer of protection against malware for workstations and servers. This service works by redirecting web traffic for sites that are known to be hosting malware.  Users attempting to browse a blacklisted site are instead returned to an IP address of a  MOREnet hosted web server. 

Features and Benefits

Malware is frequently hidden in advertisements and legitimate web pages, and users aren’t aware they are at risk of infection.  BHDNS is very easy to use; system administrators just need to replace the DNS addresses of MOREnet's traditional DNS servers with the BHDNS servers. If IP addresses are assigned by DHCP, this transition is very quick and easy to do in the DHCP configuration. Local DNS servers can point directly to the BHDNS servers.

Eligibility and Accessing the Service

A MOREnet connection is required to access the service.  Member sites that manually assign DNS entries will need to visit each computer to make the changes.   We do not recommend using the BHDNS server IP addresses for DNS resolution on mail servers.
