AAISP Secondary DNS review
Low-cost secondary DNS with AXFR/IXFR, NOTIFY, IPv4 and IPv6 support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AAISP Secondary DNS provides authoritative secondary DNS infrastructure for customers who operate their own primary DNS servers. It is aimed at technical and professional customers seeking basic redundancy for authoritative DNS without moving primary-server operations to another provider. The service copies zones from customer-managed primaries and serves them through AAISP’s secondary-dns.co.uk infrastructure. It supports both IPv4 and IPv6 master servers, giving it a practical fit for environments that need either address family.
Pricing is straightforward: the DNS plan costs £1 per month, plus VAT, with monthly billing. The plan provides the secondary DNS service for customer-operated primary servers rather than a broader set of separately priced tiers. Zone transfers use AXFR or IXFR, while DNS NOTIFY messages can signal zone changes. SOA serial checks against primary DNS servers add a basic consistency check before updated zone data is served. AAISP-hosted domains also have control-page DNS management.
The main trade-off is operational workflow. Customers configure firewall rules and primary-DNS ACLs, then request domains and master IPv4 or IPv6 addresses through AAISP support. Domain and master updates are handled by email, so this suits teams comfortable with a support-led process more than operators seeking programmatic provisioning or API-based management. The service is a sensible choice for low-cost secondary coverage around an existing primary DNS setup. Organizations needing automation, a richer management interface, or broader platform controls should consider an alternative secondary DNS service.
