Not exactly. The 3 IPs that are returned for proxy.heroku.com are not fixed. They are a just subset of the available front-end proxy servers.

Example djbdns/tinydns by default "only" returns up to 8 IP addresses so if you setup more then that those IPs will be randomly returned. http://cr.yp.to/djbdns/balance.html http://cr.yp.to/djbdns/balance.html
