DNS is one of the important names in web-based information technology that allows users to be able to browse the desired information. DNS service has some similarities with a list of phone book that stores telephone numbers and addresses. To perform the function, the DNS service configured on a special machine that serves the request is a DNS Server. The reliability and accuracy of a DNS server in providing information must be maintained. However, there are times when a DNS server fails to function normally and provide good service. Therefore, in this study, the DNS servers are surveyed and evaluated where they are installed on public universities scattered throughout the provinces on the island of Sumatera, Indonesia. The accreditation standard BAN PT rank is used as a reference mapping and evaluation of the DNS Server. To evaluate the DNS Server, the test is done by DNS health approach considering factors: response time and reliability. The results show that the majority public universities DNS Server health is good and only a small portion that needs to be addressed so that the service information is not compromised. To cope with the problem of DNS Server health, it needs to evaluate the DNS server regularly, always get the DNS Server benchmarks and adopt a variety of settings from the website of the prestigious universities so that the performance of DNS servers always provides the best service.
