.lu domain regulations

Residency requirements

This extension doesn't have any residency requirements.

Technical requirements

.LU domains require the DNS to be active on different subnets and to be authoritative for the domain at the time of registration.
You can check if they pass these minimum requirements using our Zone Check tool.


.lu domain registrations are immediate.


Once requested the transfer of the domain, dns.lu will send an email to the email account of the administrative contact for acceptance.

If the transfer hasn't been accepted two weeks after the transfer, it will be cancelled.

Note that the restart or cancel of the transfer is a non-refundable fee of 4 €, so we recommend you accept it as soon as possible.


Renewing your .LU domain only takes a minute and can be requested at any time. The process will not be completed until the current expiration date arrives.


It's impossible to cancel once they've been registered, you must wait until the domain expires and not renew it.

DNS modifications

DNS modification is immediate, please note they must propagate through the network, this process can take up to 6-12 hours to complete, until then the domain will still point to the previous DNS servers.


We allow the usage of DNSSEC on .lu domains. Your domain can take advantage of this additional security layer that DNS servers that are compatible with this technology can provide.
More information is available at: DNSSEC: What is it and how does it work.

Domain owner change

To perform .LU domain owner changes you will need to open a ticket from your client area.

Permitted characters / IDN

.lu domains permit characters from 'a' to 'z', numbers from '0' to '9' and hyphens '-'.
A hyphen '-' is not permitted in the first or last position of the domain name.
Two consecutive hyphens are not permitted in the 3rd and 4th position.
IDN characters are permitted in .lu domains.

Permitted IDN character table for .lu domains

An Internationalized Domain Name (IDN) is a domain name that can contain non ASCII characters.

Unicode Script Hyphen (-) Digits (0-9) Characters (a-z)
By default Yes Yes Yes

IDN domains don't permit to mix different Scripts or character sets (for example, Latin, Greek or Cyrillic).
But it's possible to use different character tables for a same script.

  • The Latin Script permits the use of characters of Latin-1 supplement, Latin Extended-A, Latin Extended-B, etc.. tables.
  • The Greek Script permits to combine characters of the Greek, Greek Extended, etc.. tables, doesn't permit combine them with the normal latin characters (a-z), but permits the use of numbers or hyphens.
  • Other script types have their own corresponding tables.
