ToolBox -  has 6 nameservers to ensure redundancy for domain name hosted with our service.

When registering a domain name or transferring a domain name to be hosted with us, set your dns servers to: (ipv4/ipv6) (ipv4/ipv6) (ipv4 only) * (ipv4/ipv6) (ipv4/ipv6) (ipv4 only) *

At minimum use at least 3 of our nameservers, yet we recommend you use all 6.

* ipv6 coming soon.
