[ale] DirecTV DSL - No Reverse DNS

[John Mills]

Jerry -

Thanks for clearing that up, but I'm not sure how it affects the other
reader's comment that inability to do reverse lookup would prevent them
from running a server. I have certainly seen the reverse case: servers
which will not respond to me as a client for which [I've assumed] they
cannot to a reverse lookup.

How does one check? I used 'whois <my_IP>' with no match.

Thanks.
