Zones stay on the nameservers you were given.
This console is for issued operator accounts. Transfers, signing and reloads follow the settings already stored for your organisation.
Transfers
AXFR runs when you name a hidden master for the zone.
Reload
TTL edits apply on the next reload, not when you save.
Signing
DNSSEC uses the keys already stored on the account.
Access
Only issued logins can open the console.
