That's because there's no reverse DNS entry for your IP.  You'll
have to try to talk your ISP into setting up reverse DNS entries for
their IPs..

[jim@corp:~]$ nslookup ppp01.sneaker.net.au
Server:  ns.triax.com
Address:  209.222.164.2

Name:    ppp01.sneaker.net.au
Address:  61.8.14.32

[jim@corp:~]$ nslookup 61.8.14.32
Server:  ns.triax.com
Address:  209.222.164.2

*** ns.triax.com can't find 61.8.14.32: Non-existent host/domain

If they don't add reverses for their IPs, it doesn't look like you'll
be able to get into the ftp site you're trying to get into.

Hope this helps,
