That’s because you just happen to be supplying an IP address instead of a hostname. The kernel has no DNS resolving functionality. It cannot resolve hostnames into IP addresses without help either by the caller or by means of an upcall. That is why ‘addr=’ has been a mandatory parameter ever since we introduced the text based parser.
Now we could, theoretically, have the client call nfs_dns_resolve_name() on the hostname to resolve it. However that breaks when you have net namespaces and such, since the kernel’s dns_query() call is not container aware.
