Most definitely not, and if this were 1985 I'd be {rf}commenting on the inadvisability of such hostnames, and those beginning or ending with "-", TLD names shorter than 2 or longer than 4 characters, spaces in hostnames, [^a-z0-9\\-\\.], and other such marginally useful but infinitely problematic features.
