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.
