You need to be very careful about definitions here.  Underscores in host names 
are indeed, not allowed, but they are perfectly legitimate in domain names.  
That's how, for example, DKIM key records can be in a TXT record at 
_domainkey. without fear of colliding with a legitimate host.

I'm not sure from the context if you are talking about hosts or domains, but 
make sure you know.
