I am setting up DNSSEC for our websites (via Cloudflare and our registrar Namecheap), but I cannot find clear information about if I need to do something separately for the subdomains that are forwarded to the main website.
For example, I set up DNSSEC for the website example.com, but we have a few old domains that we now forward all traffic to this domain (e.g. olddomain*(dot)com and olderdomain(dot)*com). The redirects happen through our web hosting company (Kinsta). Should I set up DNSSEC for these forwarded domains via Cloudflare and the domain registrar even though they get forwarded?
Additionally, we have a subdomain of the main domain let’s call it https://sub.example.com. This domain is a separate Wordpress installation from the main domain. Do we need to do anything special with the DNSSEC to support this?
