This paper describe the implementation of a Dynamic DNS Service, realized inside INGV, used by seismic stations using an internet connection with variable IP address, to definitively solve the problem of using a private provider, not fully compliant to INGV working needed or too expensive, in their business solution. The realized system solves different issues verified, primarily about unavailability of request domain name, limits on account management and the service’s purchase, offering an easy control system for end users.
