I’m not a dreamhost employee so I can’t see the same things as DH_Elle S. From public DNS tho, I can see that your original request was for an A-record value of 220.127.116.11 . The link above (whatsmydns) is reporting a slightly different IP 18.104.22.168
The other IP being reported 22.214.171.124 is a dreamhost shared server. If you have just changed the “fully hosted” to “DNS Only” give it time to propagate (4-12 hours) and that will make this part will go away.
You might click the DNS button under the domain name and double check the custom A-record you entered.
Rechecking the whatsmydns link now I can see the dreamhost IP is on the way out… so just double check your custom record and you should be all set.
