I don't think of it as heroku suggesting that you have to do it with a CNAME, but Neil's post highlights why you might want to. http://neilmiddleton.com/the-**dangers-of-a-records-and-**heroku<http://neilmiddleton.com/the-dangers-of-a-records-and-heroku/>
I think of it like apple including their 'time machine' backup software means you'd buy a backup drive. They aren't saying you absolutely have to do it, but its a good idea for a variety of reasons. You can use an A record and the ip addresses, it will work fine, but if there is an outage and they have to bring your app up on other IPs, you'll at least have a heads up for what you can do about it. Personally I like dnsimple.com, so I don't think of it as an extra thing I have to do, but as an extra reason I like their service, like they are helping me manage my app in a way that stays current with hosting on a cloud solution like heroku, openshift, cloudbees, etc. On Tue, Apr 3, 2012 at 7:32 PM, Justin Collum <jcol...@gmail.com> wrote: > So to use Heroku the way they'd like me to -- without an A record pointing > to an IP address -- I'll have to use a third party paid service?
