hostbased authentication/reverse name lookup

[Jeremy Peterson]

Hi,

I'm not sure if this is the right place to post this... sorry in advance if 
it's not.

I've been trying to use ip addresses for hostbased authentication. It 
doesn't seem to work unless the ip addresses can be reverse resolved. I've 
found some messages related to this. In fact, it seems that this question 
was asked before on this list, but I could not find a direct answer to this 
question.

Is it possible to use ip addresses that cannot be reverse resolved for 
hostbased authentication?
If so, how?
If not, why not?

Is there any documentation I missed?

Thanks,
JP
