Welcome to Addition Networks

Addition Networks, a division of the Merrimack Education Center, is the largest non-profit ISP and technology services provider to schools, cities and towns, and other organizations in Massachusetts. 


On October 8, 2015 we will be implementing a new Jive hosted VoIP system. We anticipate there may be intermittent loss of telephone connectivity on this date. If you are unable to contact us during this window please email support@additionnetworks.net.
