No-IP is one of the oldest and most recognised DDNS providers, with a large free tier — but it comes with a catch: free hostnames expire every 30 days unless you manually confirm them. NovaDNS never expires your hosts.
No-IP's most criticised feature is its free hostname expiration policy. Every 30 days, free-tier users must click a confirmation email or their hostnames are deactivated. This is designed to push users to paid plans, but it creates real operational risk — if you miss the email, your home server, NAS, or security camera goes offline silently. NovaDNS hosts never expire.
No-IP uses a shared username and password for updates. This means every device on your account uses the same credentials, and rotating them affects everything at once. NovaDNS generates a unique 64-character token per host — rotating one host's token has zero impact on others.
Both services support IPv6, but NovaDNS maintains A and AAAA records simultaneously without any extra configuration. Every host is dual-stack by default. On No-IP, IPv6 setup requires additional steps and isn't available on all account types.
No-IP's paid plans start at $3.99/month for 5 hostnames, rising to $9.99/month for enhanced features. NovaDNS paid plans start at $5/month with 25 hosts, significantly better value per hostname at scale.
Verdict
No-IP is a solid legacy choice, but the monthly confirmation requirement is a recurring pain point that has caught countless users off-guard. NovaDNS gives you a cleaner experience with token-based auth, a modern dashboard, and hosts that stay active without reminders.
3 hosts, no credit card, no expiry.
