Leading the world in sustainable networking.

Men&Mice is one of the oldest tech companies in Iceland and a world leader in sustainable network management. We offer a portfolio of products that makes networks more visible, manageable, resilient, and ultimately safer.

Over 30 years, our technology and reach have evolved. Today, we work with Fortune 500 companies, universities, hospitals and local governments to make their DNS, DHCP, and IP address management easy.

Our global headquarters is based in Iceland, and we have expanded to open offices in Europe and the United States.
