Registration

No minimum specified; tacit/automatic renewal. Maximum 10 years at some registrars.

Transfer Procedure

Manual transfer process. No auth code used by this registry.

Renewal & Deletion

Domains tacitly renewed. No action required to renew. Registrar must actively request removal before expiry if not renewing.

Restore / Redemption Grace Period

30-day quarantine period after deletion/expiry. Only former owner can restore during quarantine. After 30 days, new registrant can register.

NIS2 Compliance

Luxembourg NIS2 transposition applies. RESTENA ISO/IEC 27001:2022 certified (recertified March 2025).

Known Error Codes & Notes

No auth code: Transfer uses email confirmation, not auth code. Frequently misunderstood.
~15 day transfer: Transfer takes ~15 days. Much longer than most ccTLDs.
