Setting up subdomain using google domains

Question

I have a domain that I bought on Google Domains, and have a website hosted on it using Hugo + Netlify. I'd like to use a separately hosted blog website based on Jekyll on a subdomain with the name blog.example.com.

Looking online I was able to find - https://support.google.com/domains/answer/6072198?hl=en, which it seems like will re-direct the subdomain to a different web address, but not exactly allow me to host my site on that subdomain.

Can anyone explain to me how I can go about doing that?

Answer 1

You will need a CNAME record in your Google DNS: blog.example.com will point to 192.0.2.4 (use the IP given to you)
Then the subdomain blog will be in the hands of your blog hosting provider.

If there is a CNAME record for *.example.com, you will need to replace that by www.example.com to point towards your example.com A record (which points to your default website host's IP)
