Re: ftp-proxy headaches

[Nick <nagray@austin.rr.com>]

I addressed this a couple of days ago and I am dealing with the same 
issues. So I wonder if the developers are sleeping on the job or what. The 
reverse name aspect of DNS is functionally broken!. In the 'good old 
days' > 8 years ago or so, it (reverse name lookups) served a purpose. Now 
that the Internet has become a commercial venture they really don't do much 
for you. Since I, and a good percentage of the world who use the Internet 
lease out IP address space from a provider and either run our own name 
servers or lease that function out to someone else the forward and reverse 
names don't do much. Tie this in with fact that a good percentage of people 
use private networks and natting, what is the point. If I look up my dns 
name I get my address If I look up my ip I get a road runner address. 
Anyway food for thought :-)
