My ISP (Verizon FIOS) has been assigning me IP addresses that are on blacklists from a variety of third-party spam blacklisting services.
I discovered this when I was unable to create a new account at a number of different email services. Tech support at one of them advised me that using a blacklisted IP address was a common cause of the issue and gave me a couple of web addresses that check your IP address against the different blacklisting services (e.g., https://www.whatismyip.com/blacklist-check/?, and https://www.whatismyip.net/tools/ip-blacklist-check.php). Sure enough, my IP address was on nine different blacklists.
Verizon tried assigning me new IP addresses from three different ranges and blocks of available addresses. Every one was on the same blacklists. Then for weeks, they claimed they were fixing the issue, or that it was fixed, but nothing changed.
Finally, one of their support people advised me that blacklisting goes hand-in-hand with dynamic IP addresses and Verizon doesn't bother doing anything about it. However, if I wanted to pay more and get a business account, they would give me a static IP address, and that would be clean.
I'm aware that years ago, there were problems like ISPs with open relays that caused all of their IP addresses to be blacklisted. Also years ago, I ran into issues with spammers using blocks of IP addresses, which got the addresses blacklisted. Then one of those IP addresses would be assigned to me and I would need to work through the ISP to get it off the blacklists.
Blacklisted IP addresses are apparently still an issue, but ISPs not fixing the problem can't be the standard, or nobody would be able to get online accounts. So I'm trying to get a better handle on the issue and what can be done to fix it.
- Is there anything I can do, myself, to deal with the blacklisting services, collectively, to get my address removed from the lists each time I'm assigned a new one (it doesn't look like the blacklist services are set up for that)?
- Is it reasonable to expect my ISP to be able to get their IP addresses removed from the blacklists (i.e., is it just a case of Verizon having a monopoly in my area so they have no incentive to expend even a penny of resources to address a fixable problem, or is spamming associated with dynamic IP addresses an intractable problem and ISPs no longer deal with it)?
- Is the blacklisting and its removal regulated by any entity that might be a source of leverage to get the issue fixed?
