Why can't we have CNAMEs for PTRs? (self.sysadmin)

Silly question: Having CNAMEs for A records just makes sense, but why can't we have a PTR redirect?

Thanks for that - I hadn't thought about the rest of the domain in the name.

I was purely thinking about it from a hypothetical risk-mitigation perspective.

As you can imagine, keeping 'the old crap around' in case of a need to roll back would be handy in some migrations... Assuming the same IP complicates that.

However, I guess a machine can have multiple IPs so it needn't be too much of a drama if it's just a matter of moving the original IP when rolling back...
