What you will be able to check
- Identify the services connected to your domain and who is responsible for them.
- Confirm the registered holder, the contacts and the access you need.
- Prepare for access recovery, renewal and a change of people or providers.
STEP 1 OF 5
Understand what depends on the domain
The aim A clear picture of the domain, website and email services.
Before looking for a password, find out which service it gives access to.
Within a business, the domain, website hosting and email are often referred to by the name of the provider looking after them. ‘It is all with our agency’ may cover several suppliers and several accounts.
Four separate elements are worth identifying:
Domain name
The name used for your online presence, such as company.lu
What to findThe registrar and the registered holder
DNS
The records that direct users and systems to the services connected to the domain
What to findThe DNS provider and the people authorised to make changes
Website hosting
The resources that run the website and store its data
What to findThe hosting provider, the administrator and the backup arrangements
The service that manages mailboxes and their messages
What to findThe provider and the account administrator
One provider may supply all four services. Their functions remain separate: registering a domain does not, by itself, provide website hosting or email accounts. The my.lu guide explains this distinction.
DNS records connect the domain to its associated services. Their configuration affects both the website and email, as explained in the DNS Luxembourg glossary. That is why work carried out for the website can have consequences elsewhere.
Ask your provider to help complete this overview with the relevant accounts and contact details. Include less visible uses: an old address that redirects visitors, a subdomain or a tool used by only a few employees.
This overview will be useful when changes are next made. Before a website redesign, for example, it helps you agree what will change and who will then check the website, outgoing email and incoming email.
STEP 2 OF 5
Confirm the registered holder
The aim A confirmed registered holder and up-to-date contacts.
Once the services are identified, one central question remains: in whose name is the domain registered?
The answer is not necessarily on your agency’s invoice. The person paying the bill, the person making changes and the person or organisation recorded as the holder may be different.
Obtain confirmation of the registered identity from the management account or the registrar, and keep a dated copy. If you find the name of a founder, a former employee or a provider, ask why that name is on record and what steps would be needed to put the arrangements in order.
The registered contacts matter too. The my.lu guide distinguishes administrative, technical and billing contacts, and explains that the administrative contact must be authorised by the holder. These roles are separate from the permissions needed to log in to an account. See My domain name.
What WHOIS can tell you
For a .lu domain, a WHOIS lookup provides a useful starting point. However, only some registration data is public: the identity of an individual holder is hidden, apart from their country of residence, and administrative and technical contact details are hidden by default.
Missing information in the public results does not necessarily indicate a problem. The DNS Luxembourg WHOIS page explains these limits. Ask the domain manager for the information you need.
If a change is required, establish exactly what kind. Updating contact details, changing the registered holder and transferring the domain to another registrar are different operations. The .lu registry describes a change of holder and a change of registrar separately. The published procedures provide for approval by the current administrative contact.
Migrating a website is a different task again: moving its files does not, by itself, change the domain’s registered holder.
STEP 3 OF 5
Check access and recovery arrangements
The aim Tested access and a documented recovery process.
Knowing where the domain is managed does not yet mean you can act. An account may be known but inaccessible, or provide only limited permissions.
With an authorised person, try logging in at the official management address. Check the permissions available: being able to view an invoice does not necessarily mean you can change DNS records or manage users.
Protecting access deserves as much attention as making it available. ANSSI recommends separate passwords and two-factor authentication where it is offered. Its digital security guidance also explains the benefits of a password manager.
Then ask: what happens if the usual way of signing in is no longer available?
Depending on the provider, recovery may involve backup codes, another authentication method or a request to support. Ask for confirmation of the steps and the evidence required. A process known in advance is easier to follow than one discovered during an outage.
Where the service allows it, individual user accounts with appropriate permissions make responsibilities easier to share. They also allow one person’s access to be removed without disrupting everyone else.
When an employee leaves or a contract ends, review the relevant permissions, recovery contact details and authentication methods. Record the process and where the backup methods are securely stored in your management record. Keep passwords and codes separately in a secure vault.
STEP 4 OF 5
Organise renewal
The aim A renewal deadline monitored by a named person and a backup.
Renewal often seems settled once it is automatic or delegated to a provider. Its outcome still needs to be checked.
A replaced payment card, a notification sent to the wrong inbox or an unclear responsibility can allow a deadline to pass. For every domain you intend to keep, Wize suggests documenting four points:
| Point | What you need to know |
|---|---|
| Deadline | The date given by the domain manager and when action is required |
| Payment | How renewal works, the payment method and who monitors it |
| Alerts | The recipients and the person responsible for reading notifications |
| Confirmation | The person who checks the result and keeps a record |
An internal reminder should leave enough time to resolve an access or payment problem. If the domain is included in an annual package, ask your provider how renewal is monitored and how you receive confirmation.
Remember secondary domains
Include old addresses and less frequently used domain names in your review. A domain with no visible website may still receive email or redirect visitors.
Before giving one up, have its uses checked and record the decision. The absence of a website or apparent traffic is not enough to conclude that the domain is no longer needed.
STEP 5 OF 5
Prepare for continuity and handover
The aim A management record that someone else can use.
These checks become most useful when they enable another authorised person to take over.
You can delegate day-to-day work to a provider while retaining your ability to make decisions. Agree in writing which operations are delegated, which require your approval and who is responsible for monitoring renewal.
Also establish who to contact during an incident, which documents will be handed over at the end of the contract and how management can be transferred. For a .lu domain, make sure the registered administrative contact remains reachable: the registry stresses the importance of an accessible email address in its registrar transfer process.
Bring the useful information together in an internal record:
| Information | What to keep |
|---|---|
| Domain and uses | The exact name, connected services, redirects and relevant subdomains |
| Holder and contacts | Confirmed identities, roles and supporting records |
| Registrar | Name and official address of the management account |
| Providers | Contacts, contact details and each provider’s responsibilities |
| Access and recovery | Authorised people, the process and where backup methods are securely stored |
| Internal responsibility | The person responsible and their replacement |
| Renewal | Deadline, payment, alerts and confirmation of the result |
| Follow-up | Date checked, outstanding points and the next review |
Where to start if information is missing
Gather the invoices, registration confirmations and existing correspondence. You can then send a precise request to your contact:
Ask your provider To update our management record, could you confirm the registered holder and contacts, the registrar, the management account address and the renewal arrangements?
Please also explain who manages the DNS records, which services depend on them and how another person authorised by our business could take over.
If an update is needed, please explain the operation, the approvals required and any possible consequences before making the change.
Keep the response with your record. Following a departure, a change of provider, a migration or a change to payment arrangements, review the relevant points. Updating the record is part of the handover.
Five questions to review
- Which services depend on our domain, and who manages them?
- Who is confirmed as the registered holder, and who represents them?
- Can we log in and recover access if needed?
- Who checks that renewal has actually been completed?
- Who takes over, and where can they find the information?
For each unanswered question, record the information needed, who will obtain it and a deadline. You will have an action plan to follow with your provider.
