You can use logical operators (ie AND, OR) in expressions, I think
it's in 'man dhcp-eval'.
Also, have you considered subclassing ? There's a section (including
example) in 'man dhcpd.conf' - just replace all references to MAC
addresses with RID/CID. IIRC, it's said to be more efficient than
large "if x or y or z or ..." constructs due to hashing.
