1&1 IONOS offers comprehensive DNS management in which you can set all of the important settings for your domains and subdomains.
DNS settings are often required to link your domain to other services, such as with SquareSpace or Wordpress.com. Another common application is that DNS settings are necessary to verify your domain with other external services, such as MailChimp. For many of these scenarios, we have already prepared step-by-step instructions.
1&1 IONOS allows you to specify your own name servers for each domain instead of the default 1&1 IONOS name servers. This allows you to designate the DNS management of your domains to another provider or to host your own name servers.
With the 1&1 IONOS name servers, you can also connect your domain to static IP addresses. Both IPv4 and IPv6 are supported.
For subdomains, 1&1 IONOS also offers the possibility to configure a CNAME instead of an A record. This allows you to set up a subdomain as an alias for an existing domain.
By editing your MX records, you can set your own mail servers for each of your domains if you want to use another mail provider.
For advanced applications, 1&1 IONOS offers the ability to configure your own TXT and SRV records for your domains and subdomains.
