 I already have a domain registered using someone else. Can I still use Nettica for DNS?

Yes. You do not need to register or transfer your domain to Nettica to use our DNS services.

まともな説明

How long does it take for a Nettica static DNS entry to change?

Changes you make using our management interfaces are real-time. Once you click OK the changes have been made. However, because DNS is a caching system, it can take up to an hour for caching DNS servers to expire their entries. If you are about to make a DNS change, we recommend that you not ping the address just before the change, or you may have to wait until the timeout to see the update.
