When you map a custom domain to App Engine, you use a CNAME entry that
points to some-host.your-domain.com.

Our products often use a dynamic, programmatic hostname, e.g.,
[dynamic-host].our-domain.com.

Google Apps supports a wildcard host mapping, which is great.

However, our domain registrar (GoDaddy) does not support a wildcard
CNAME, they only support a wildcard A record. So, we've hacked it to
use an IP address that ghs.google.com resolves to, knowing this is
fragile.

And, of course, one of the IP address that we were using for
ghs.google.com changed sometime overnight and our sites broke.

Does anyone know of a registrar that supports wildcard host matches on
CNAME records. It seems that GoDaddy.com and register.com do _not_.

Or, any other solutions? (I definitely don't want to front this with
my own proxy.)

Thanks,
j

Not a registrar, but we use http://www.dnsmadeeasy.com/ for DNS hosting and they support it.

Also not a registrar, but Amazon's AWS Route 53 DNS service supports wildcard CNAME's that can be used for GAE as well.

Hi Jason,

You don't need to change your registrar - just your DNS host. I believe zoneedit support wildcard CNAMEs.
