    Hostnames may begin with digits. What makes you think they can't? This was
    fixed eternities ago thanks to 3com.com ;-)

    As for having a hostname be a dotted quad, just be aware what it will
    either be used as an IP address directly (bypassing name services
    entirely), or be looked up as 1.2.3.4.dns-domain-search-path (assuming
    you're using DNS as your host name service), depending on the application
    used, and the resolver library in question.
