Why do you think an fraudster would even use a VPN... To avoid the blacklists you know. If the fraudster did the fraud on his residential IP his own IP would be blacklisted.

This is excellent. Fraudsters would never be smart enough to use residential IPs as a proxy (zombie computers, open wifis, and mobile internet are myths), nor would a legitimate customer ordering from

Problem would be with that I don't know every residential ISP their CIDR range. Even if people from LET knew alot it would be massive trouble if there is atleast 1 residential CIDR range thats not whi

Also, FYI, you might as well just block all ranges except for residential.

I, or WE, do not block anything, maxmind blocks proxies at ordering, but you can do it in many ways, either whitelist (I would go with that) meaning you add all US ISPs which offer residential service

One way of avoiding this, would be to get some super fast residential connectivity and proxy using that.

* Host your own mail, only use it over smtps/https/pop3s and encrypt the storage, preferably host it at home and pipe it through some VPS you own because dynamic ranges or residential ones are usually

Residential, but server works too. I've sent you a PM.

Did you try from a residential ip or a server ip

sure you'll get that...since you are not using residential ip....but DC ip...this will surely block those undetected proxies or vpns....

While we have a few plans like moving all hosted Remote Desktop machines to go behind a gateway, the only real solution is to start forcing people onto IPv6. Unfortunately the rollout of IPv6 from ISP

Sorry, I might've not said things clearly. I'd like to be able to detect mobile networks, not necessarily mobile devices. For example, if it's an ipad that's connected to a residential ISP via wifi, I

As to IP ranges, they could just use wifi networks and as previously said a large chunk of mobile operators are also residential ISP's.

Exactly the issue I'm having. AT&T and other providers offers mobile and home internet and I can't differentiate between the two with accuracy. I assume they don't have a residential IP that a

Rather, most telcos just can't be bothered to move to IPv6, or provide it to residential connections.

I'm able to max out my residential DSL line with the speed test.

In general, the islands in and surrounding the Caribbean do not have good internet connections. Even slow internet is expensive. For example, when I last checked (a few years ago), 128kbps ADSL (note

Its not spoofed IP traffic. The IP's, most of the time, are legitimate residential connection IP's, and the owners have no idea that they are participating in a DDoS attack. Blocking the IP's would pr
