It looks like there's a few similar questions but they all seem to want to do this through various HTTP redirects, and I'm looking to do this purely through DNS.
Basically I'm trying to forward all subdomains of a given domain so they resolve to the same-named subdomain of another domain.
E.g.
*.foo.com -> *.bar.com
Therefore any domain would resolve:
blah.foo.com -> blah.bar.com
garbage123.foo.com -> garbage123.bar.com
maybe.ifimlucky.foo.com -> maybe.ifimlucky.bar.com
I'm looking for a product-agnostic solution. Is this possible, or am I stuck wiring up each subdomain manually?
