Active domain name

A domain name is active when its delegation details (authoritative name servers) are transmitted and when it is published in the .lu zone. The domain name may then be used for services such as hosting websites or for electronic mail. 

DNS servers

A DNS server or names server is a computer connected to the Internet. It contains information about the services related to a domain name and answers any queries about this information. For example, it translates a domain name into an IP address to enable access to a website/s and/or email inboxes linked to a domain name.

Inactive/reserved domain name

A domain name is inactive when its delegation details (authoritative name servers) are not transmitted and when it has not been published in the .lu zone. As such, the domain name may not be used for services such as hosting websites or for electronic mail. 

IP address

An IP address is a technical identifier, assigned to each piece of equipment connected to the Internet, and that these use to communicate with each other. There are currently two formats of IP addresses: IPv6 and its predecessor IPv4.
