Dnsmasq treats client-ids as opaque blobs, with a single exception that 
acknowledges the "zero type is string" convention. If a client-id starts 
with a zero, then an attempt is made to match against any configured ids 
both with and without the zero. So a configuration option like this:

dhcp-host=id:"fred",1.2.3.4

will match (and assign a fixed address to) both client-id

'f' 'r' 'e' 'd'

and

'/0' 'f' 'r' 'e' 'd'

Cheers,

Simon.
