Doing a shell exec to host or dig is a very doable. Go for it.

Also there is Net_DNS. Peaking in the code reveals it uses fsockopen() and reimplements the DNS protocol(s). You can use it under PEAR, or just shred the code to your liking, LGPL.

There are probably more code snippets out there, but that's enough hunting for today.

Happy coding!
