The DNS is used by many programs to translate hostnames to IP addresses and vice-versa.
If you are running a PC or very simple server, you will probably want to use the DNS resolvers provided by IITS. Please use these two IP addresses as your "DNS servers":
If you want to set up your own subdomain of "concordia.ca", please contact the Hostmaster <firstname.lastname@example.org> for more information. IITS provides DNS secondary services for subdomains of "concordia.ca".
Note that we do not provide general DNS resolution services to hosts offsite; those hosts may query us only for the information we "NS" for, that is, information under ".concordia.ca" and in our network "132.205.*.*". (This ban is enforced on some of our nameservers; it may eventually be enforced on all of them.)
The above affects you only if you connect to the net from home using an ISP; in that case, please make sure that you configure your home computer to use your ISP's nameservers, not Concordia's.
