IPv6 DNS
IPv6 is a DNS record and a DNS transport.
Applications that added IPv6 still publish only A records, or host DNS on IPv4-only nameservers, so dual-stack clients never see the path.
Cloud DNS supports IPv4 and IPv6 records and transport. Publish AAAA beside A, and serve the zone from Anycast nameservers that speak both.
Why teams use Aptranet
How it works with Aptranet
Cloud DNS combines Anycast resolution with traffic steering and health checks. Growth and Business support TTLs as low as one second.
AAAA records on Anycast
Dual-stack applications can be published without a second DNS vendor.
IPv6 nameserver transport
Resolvers can query authority over IPv6 as well as IPv4.
Same steering as IPv4
GeoDNS, weights and health checks apply to the records you publish, including AAAA.
How to set it up
Validate your setup before production changes.
Configure your Cloud DNS zone and verify its records and routing policies. Test answers from the authoritative nameservers before changing your domain delegation.
- 1Add AAAA records for dual-stack endpoints
Only for infrastructure that actually speaks IPv6.
- 2Health-check the AAAA targets
Do not publish an address you cannot probe.
- 3Delegate with IPv6-capable NS
Cloud DNS Anycast nameservers support IPv6.
- 4Verify from an IPv6 client
Confirm both lookup transport and application connectivity.
Outcomes
What changes once the hostname is on Aptranet.
- AAAA records can go live beside A
- Authority is reachable over IPv6
- Steering policies include IPv6 targets
- Health checks can watch AAAA endpoints

Frequently asked questions
No. Publish AAAA when the endpoint you return actually accepts IPv6. Cloud CDN can still deliver over IPv6 to clients.
Yes. Sign the zone, including AAAA records.
Policies apply to record sets. Design IPv4 and IPv6 maps so they do not disagree in surprising ways.
Vanity nameservers are supported. Include AAAA glue where the parent requires it.
