The nameservers for all of the domains managed by DreamHost, including ‘dreamhost.com’, are set up using the following:
- ns1.dreamhost.com 22.214.171.124
- ns2.dreamhost.com 126.96.36.199
- ns3.dreamhost.com 188.8.131.52
If you're updating your nameservers at your registrar, you should only have to add the nameserver URL, not the IP. The IPs are listed above just in case your registrar asks for them.
If your domain is registered with DreamHost, the panel will show the option of setting these DreamHost nameservers without needing to enter the information above.
If your domain is registered elsewhere, the change to your nameservers will have to be done with the current registrar of that domain name. The details above can be set with the current registrar to point the DNS management for your domain to DreamHost. This way, DreamHost can manage the DNS settings for you through the (Panel > 'Domains' > 'Manage Domains’) page in your panel.
It's recommended that you point your nameservers to DreamHost. This makes the management of your DNS simpler as all records can be found within your DreamHost account.
