It is quite possible you inherited some of your ips from a spammer
but I would have to research that some more.
For the dedicated ips you can just call your ISP and ask them to change the ip.
There is several users who posted in this thread and said they were having problems - when I checked most of those users were from the same ISP but you don't belong to that ISP.
As I posted there are a few databases that come back with a problem for every IP my provider supplies. Unless you are using a TOR browser or just posting via a proxy you are going to be out of luck. New IP or not.
Most people don't have the luxery of a static IP. You usually need to pay for that and there is rarely a need to have one unless you are hosting something.
I'd bet if they checked, everyone would come up with the same set of failed databases. It would not surprise me if it was these ones.

Even if you were lucky to have a static IP, there is a good chance it would fail too.

Is there any way to check who is failing what database check? If anything, that is going to be your overall common denominator, not the IP.
You don't even have to get a new IP. Just change the last number or two and you should continue to get failures.
Something changed after the crash, This was never an issue before. It is not an issue on any other site (at least for me). The check is far to probably rigorous.
If you can't check a log then why not post a sticky asking people to report back on the failed databases?
It would not surprise me if this issue is far more than just a few people. There are those you just have not seen this thread or simply have not logged in since the crash.
I would like to know what good it goes to be checking multiple times per session. It is bad enough checking once. Chances are the timeouts for that check and login are different settings. At the very least they should be the same value.
