EC2 servers spawned via Rightscale have reasonable nicknames like
foo_03 inside Rightscale UI. These nicknames seem to be completely disconnected from anything else in EC2 - they're not even anywhere in
/var/spool/ec2. This isn't really a big deal as I can figure them out from instance IP plus a few XML requests to Rightscale.
The question is - is there a way to get such nicknames into DNS system? I'd like
foo_03.something.com to resolve to
foo_03's IP address, and especially I'd like
foo_03's IP address to reverse resolve to
I don't need it for anything facing end user, only to see which connection comes from which server.
How difficult would it be? (
/etc/hosts hacks might be sort of acceptable I guess).
