How to route based on domain name?

I can route by IP range by the route command. But is there any domain based route solution?

Solution 1:

Routing is a layer 3 technique that gets your packets where they are supposed to go. Layer 3 information is almost only source IP, dest IP and fragmentation information.

Extra information such as domain name is way beyond layer 3, it's more layer 7 (the application layer). Therefore such information is not meant to be used for routing.

There are specific techniques that use information above layer 3, such as Policy Routing which uses layer 4 information (TCP/UDP ports) to route specific packets. That is as high as it goes as far as I know.

If you have control over that domain name, you could specify as specific IP that will then be routed by your routers in a specific way. If you can't do that, I'm afraid it's not going to be possible as far as I know.
