	Let's go back to the original message on this subject from Jørgen 
Elgaard Larsen:

| In my experience, reverse DNS often works well with larger
| organisations that have been assigned a /24 IPv4 range or
| greater. On the other hand, it almost never works with smaller
| organisations using smaller ranges, e.g. on ADSL lines.

| As I see it, there is a general trend that more and more small

| IPv4 addresses are scarce, these businesses are often assigned
| IPv4 ranges smaller than /24 - many only get a /30 range.
| Nevertheless, they still operates servers for various purposes.


	Now, Jim -- you're talking about the general solution.  Yes, with 
enough money, you should always be able to find an alternative 
provider who is willing to do whatever you want.  You just have them 
run an OC-192 line to your basement, get RIPE to issue you a /8, and 
you're golden.  Anything down to an E-1 and a /24 and you shouldn't 
have any problems.

	But we're not talking about the general solution.  We're talking 
about issues with DSL providers.

	Now that is a statement which I will agree with.
