hi, i dont think there is one similar to gethostbyname in the kernel-space. I do think so because most of the work done by gethostbyname is based on the nameservices and is generally not required in the kernel-space. Implementing it should not be that big a problem. once you have the IP of the name server (/etc/resolve.conf???) you can always connect to it and get the IP of the given host.
