i9 DDNS is a free dynamic DNS service operated on the i9.ma domain. It lets you point a subdomain under our DDNS zone at an IP address that you control, and keep that record updated automatically as your IP changes.
You're responsible for keeping your login credentials and per-subdomain update tokens confidential. Anyone with a valid token can update the IP address for that subdomain, so treat tokens like passwords.
Each account may register up to 5 subdomains. We reserve the right to reclaim inactive, abandoned, or abusive subdomain names, and to refuse names that are misleading, reserved, or infringe on third-party rights.
You may not use i9 DDNS to host or point to content that is illegal, that facilitates malware distribution, phishing, or command-and-control infrastructure, or that otherwise violates applicable law. We may suspend or terminate accounts found in violation without notice.
i9 DDNS is provided on a best-effort, as-is basis. We do not guarantee uninterrupted uptime, and we are not liable for losses arising from service interruptions, DNS propagation delays, or incorrect updates.
We may modify, suspend, or discontinue any part of the service at any time, including these terms. Continued use after changes take effect constitutes acceptance of the updated terms.
Questions about these terms can be sent through our contact page.
