Where to add to DNS settings for Google crawl

[Panda]

Running a NodeBB forum on my own Ubuntu server.
For Google to crawl site it asks me to verify page by adding a link to DNS settings
Where would I find that, is it a file in a directory on Ubuntu?

@eveh hi, no, this will be your domain provider, for example, Cloudflare. Whoever your domain is registered with.

@phenomlab
oh do you mean where I bought Domain name from?

@eveh yes, as the DNS will be natively registered there.
