My DNS information
Connect the authoritative name servers offered by the .lu registry to your domain name.
Free of charge
To be able to manage the content of your DNS zone, it is crucial to have stable and secure hosting. Consequently, authoritative servers with automatic DNSSEC security are offered by the registry to be used exclusively via the online registration platform.
All information connected to a domain name is therefore hosted with Restena which also manages the domain names registration infrastructure in .lu, with a direct connection to its master server.
A domain name is a functional identifier that is unique, understandable, and memorable to and by human beings. It enables technical information to be obtained, such as the IP address of websites or electronic mailboxes, by asking a names server (DNS server).
Advantages
- Your DS servers and registrations are automatically configured
- You benefit from a high resiliency thanks to the use of anycast servers (located across Europe in order to be in the closest proximity to visitors and their DNS requests)
- Your domain name is DNSSEC-protected
How to benefit?
The configuration of hosting may occur at two key moments in the life of a domain name.
- On its registration, at step 3 'Technical data' during the order process for a new domain name.
- When changing it, under the tab ‘Delegation’ of the domain name available via the ‘Domain names' section.

Configure at least two DNS servers connected to your .lu domain name
Free of charge
To make available websites and/or mailboxes connected to a domain name, DNS servers have to be linked to this same domain name. These computers, when they respond to address requests within the domain name system, make information connected to a domain name and, by extension, the Internet, live.
These authoritative servers are provided by Internet Service Providers (ISP) as part of their hosting service. Data from this hosting will be configured when a domain name is activated.

Frequently Asked Questions (FAQs)
I've registered a domain name, what do I need to do to be able to use it?
To be able to use your domain name for, as an example, a website and/or email addresses, you need to configure and activate your name servers.
- If you are using classic management, you must provide your own DNS servers.
- If you are using online management, you can use the DNS servers offered by the Restena Foundation or update your own servers.
You can also host your own website and/or email address. As these services are not offered by the registry, you should contact other providers.

I've changed the name servers of my domain name but it isn't working. Why not?
Any changes you make to your DNS servers do not take effect immediately. They are subject to unavoidable delays
- The timeline with the .lu registry: updated 24/7 on the hour.
- The timeline for online availability: activated within 1 hour, after changes have been made by the .lu registry.
- The timeline for changes (with existing name servers): depending on the TTL (Time to Live) related to your domain name, i.e. the time during which information in your domain name in the .lu zone is stored in memory. The TTL varies from one DNS provider to another.
- At least one of the server names is not configured or is not correctly configured for your domain name.
