So how is a proponent of the "Hunt down and kill spammers very messily"
FUSSP classified?
I'm suggesting that some homework should be done before creating a list
of this or that and then promoting it as something that it's NOT on the
SA users list.
A list of dynamic IP addresses is already available in the
correct/usable form. There's no need for a 'name based' version.
Marc said "This list was created by grabbing the registry barrier part
of the domain name of IPs from other DNS lists that list the IPs as
dynamic."
That would seem to translate to doing a reverse lookup or whois on PBL
or NJABL IPs. That's fine, but then he claims that his list is a "list
of domains that provide consumer dynamic IP address space".
But it's not. It may give you IP address ownership information if your
list is created using whois, but it doesn't tell you what ISP (domain)
assigned the address to the customer. If you are depending on reverse
lookups, then the info is more suspect, since ISPs are not very good at
keeping in-addr.arpa zones up to date. Also, many larger network
operators and ISPs trade/lease/rent consumer IP address space to other
ISPs very frequently. These addresses roam around to various ISPs. There
is no 1-to-1 mapping.
