"We’re still working out some of the details of ALIAS records, but we do feel that they are a very useful addition to the records supported by DNSimple"

Guys, have you heard of writing an RFC? Other people might like this too, and have contributions to the detail.

It seems like this is a provisioning trick, rather than an actual DNS record. None of this "ALIAS" records ends up in a zone, or in a DNS packet; rather it is some option on a web interface that presumably never comes near the actual DNS because it is provisioned as something else.

I'm curious, if you point such an ALIAS to a service that dynamically returns different IP addresses based on location; what this service is going to do.

Right now it would resolve to the location of whichever of our name servers handled the request. Theoretically we could pass through the original requestor's IP address, but we don't right now.

Seems like that would make caching the results substantially harder on your side.

So, a small limitation is that this shouldn't be used in front of a geo dns. Fortunately, it's still a great choice for the other 99% of sites.
