Home Services

Most residental internet connections use a dynamic IP address, which changes weekly or daily. This prevents visitors from easily finding their networks. The Dynamic DNS and Dyn Standard DNS services fix this problem by giving you a human-readable hostname, such as yoursite.dyndns.org or yourdomain.com, which is updated automatically with your IP with a special update client. This allows visitors to reach your home network without needing to know the IP address ahead of time.
