ice.domains Secondary DNS review
A free secondary DNS service with unlimited zones, records, DNSSEC, API access, and Anycast.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ice.domains Secondary DNS provides independent authoritative nameservers alongside a primary DNS provider. It is designed for e-commerce businesses, SaaS companies, email-critical domains, developers, small businesses, and personal projects that need DNS redundancy. The service is available through the web and API, with a focus on maintaining independently managed copies of DNS zones.
The Free plan costs $0 USD forever and includes secondary nameservers, global Anycast DNS, DNSSEC, REST API access, and unlimited zones and records. Its feature set also includes automatic import for common DNS records, query analytics, edge DDoS mitigation, and dynamic DNS updates for A and AAAA records. One-click DNSSEC signing and programmatic management make it suitable for teams that want more control than a basic nameserver arrangement provides.
The main operational consideration is synchronization. ice.domains describes its setup as primary-primary, with independently editable zone copies, rather than documented automatic AXFR synchronization. Records can be mirrored manually or updated through the REST API, so organizations should choose this service when they can manage that workflow. It is a strong fit for cost-conscious users seeking independent nameservers and broad DNS capabilities without a paid tier. Teams that require a transfer-driven secondary DNS workflow or a more automated synchronization model should consider an alternative.
