Perfectly valid, except that DNS servers are usually attached by some sort of broadcast media via a switch to the router that has the static route, and if the DNS server stops responding, the static route doesn't "go away". I have used a cross-over cable from the DNS server to a dedicated ethernet interface on the router to solve this, however, it didn't fly as it came down to not wanting to have a single underutilized interface per DNS server...Cisco ethernet ports aren't cheap (fade to other thread about using Unix/PC boxes with cheap 4 port ethernet cards as routers)...
