DNS Records: One IP for Primary Domain and One IP for Multiple Subdomain
I'm using Cloudflare (no proxy) to manage DNS Records. I have two servers with IP:
- 128.xxx.xxx.xxx
- 174.xxx.xx.x
And these are the DNS Records that I have created:
| Type | Name | Content |
|---|---|---|
| A | example.com | 128.xxx.xxx.xxx |
| CNAME | sub1 | example.com |
| CNAME | sub2 | example.com |
| CNAME | sub3 | example.com |
Now, I want to point the main domain (example.com) to the new IP (174.xxx.xx.x), the subdomains (sub1, sub2, sub3) keep using 128.xxx.xxx.xxx.
I could of course change the DNS records for each subdomain to type A by pointing all subdomains to IP 128.xxx.xxx.xxx like this:
| Type | Name | Content |
|---|---|---|
| A | example.com | 174.xxx.xx.x |
| A | sub1.example.com | 128.xxx.xxx.xxx |
| A | sub2.example.com | 128.xxx.xxx.xxx |
| A | sub3.example.com | 128.xxx.xxx.xxx |
The problem is, I have a lot of subdomains and the number is growing, I don't want to manually write the IP for the subdomains, apart from many, I'm also worried that I will switch servers with different IP addresses later.
Is there any way to solve this problem?
I really appreciate any answer, thanks in advance.
Solution 1:
You could create an A record cname.example.com, with the 128.xxx.xxx.xxx IP address.
Then for each domain, you would have CNAME point to cname.example.com.
