The models' case: Best overall value: globally distributed Anycast authoritative DNS, DNSSEC, scoped API tokens, mature Terraform support, and unmetered queries on non-Enterprise plans. The models' main caveat: Native secondary DNS, zone transfers, and robust multi-provider designs require Enterprise plans. The strongest alternative is Amazon Route 53 — The most mature Terraform/CloudFormation coverage of any authoritative provider, battle-tested global anycast, health-check-driven failover, and. Not unanimous: Claude picks Amazon Route 53.
