DNS Services

DNS (Domain Name Server) servers allow you to reach another computer on the Internet from your computer without having to provide the explicit Internet address. Users prefer to use friendly computer domain names like "library.com" instead of its IP address "172.16.23.44". The DNS is a program consisting of a database of name and address information. The program responds to queries from other programs. DNS servers can communicate amongst themselves to update one another with new information. This mechanism is what allows you to reach a webpage on a new server when a friend sends you a link. You do not have to know the IP address of the server that contains the webpage.

If you would like OPLIN to serve as the primary DNS service provider for your domains, you must notify us via email along with a list of all records in each zone. We will have the zones defined on the state DNS servers, and once completed you'll need to update your registrar with the four state DNS servers below. If you do not know who is currently providing your service, you can go to www.networksolutions.com/whois to find out. The information for the State's DNS is as follows:

State of Ohio
ns1.state.oh.us
156.63.130.100
ns2.state.oh.us
156.63.130.68
ns3.state.oh.us
156.63.130.75
ns4.state.oh.us
156.63.130.120
