Nice!

It might be better to give your hosts names that are easy to pronounce
and remember. Higher-level components of the domain name could be used
to encode information like location, organisational unit and the type
of device that the hosts belongs too. eg:
	atm0.router.sales.geneva.example.com

The example name you gave is legal, so there's no reason for the name
server to reject it. Underscores are not allowed in hostnames, though
RFC2181 says name servers should not "refuse to serve a zone because
it contains labels that might not be acceptable to some DNS client
programs". If the name server is objecting, it's a bug. By default
BIND8 rejects zones containing hostnames with illegal characters. This
should be considered a feature rather than a bug. :-) If the name
isn't in the file h2n generates or if h2n is complaining, then it's a
bug in h2n.
