Name servers are the servers that assign a specific IP address to each specific domain name that has set those name servers in its DNS settings.

They are responsible for your domain being found under a fixed IP address when the visitor types in the domain name itself, making it easier to find websites by name rather than by a set of numbers. IONOS uses its own name servers to automatically assign an IP address for a domain during the registration process at IONOS.

By default, all name server settings are pre-configured for your IONOS domain. You can configure a website, blog, or online store, and set up the appropriate email mailboxes. You don't have to worry about a thing!

Typical name server entries are:

ns1ZZZ.ui-dns.de
ns1ZZZ.ui-dns.biz
ns1ZZZ.ui-dns.org
ns1ZZZ.ui-dns.com

ZZZ represents a number between 016 and 126.
