What People Are Saying

Join the community of developers, homelabbers, and businesses who trust LockIP

Finally, a DDNS service that actually updates fast. My Minecraft server is always reachable now, even when my ISP changes my IP at 3 AM.

Homelab Enthusiast

Switched from No-IP after they started requiring monthly confirmations. LockIP just works, and the 60-second TTL is a game changer.

The API is clean and well-documented. Integrated it into my deployment pipeline in about 10 minutes. Exactly what I needed.

We were paying EasyDMARC $72/month for just DMARC monitoring. LockIP gives us Dynamic SPF, DKIM, and DMARC for $35. The switch took 10 minutes.
