Any way to identify all wildcard subdomains actually used?

Website, Application, Performance DNS & Network

Hi there – my developers have created a wildcard A entry (*.domain.com) for convenience, and it’s causing all sorts of random problems.

  • I’m trying to replace that wildcard entry by as many individual A entries as currently needed (e.g. join.domain.com, beta.domain.com, ftp.domain, etc.)
  • I’m concerned that we may forget some of the subdomains actually used by the application
  • Q: Is there a way (through Cloudflare or outside) to get an exhaustive list of all subdomains that were ever queried/accessed for my domain.com? Say, in the last 30 days.

Any and all pointers much appreciated.
Cheers,
Phil

That looks to be only available in Enterprise plans under Analytics -> DNS.
