omapi and agent.remote-id

[Jeff Waller]

You say subnets, but do you mean subclasses?  

subclasses are better because it's far more efficient in terms of lookup
complexity.  Subclass lookup is hashed O(1) while host lookup is linear O(n).  Are
you saying new to 4.2 host lookup is also hashed?

Can you define large?

Take a look at the source code for dhcp in server/omapi.c starting
around line 2640

in particular the functions

dhcp_host_set_value 
dhcp_host_get_value
dhcp_host_destroy
dhcp_host_stuff_values
dhcp_host_lookup
dhcp_host_create

to get an idea of the values that are supported

in addition, there are other supported objects, although (see my post
in January)  some of them are buggy, but you can apply my patches.
